Progressive rock (sometimes known as underground rock ) is a radio station programming format that emerged in the late 1960s, in which disc jockeys are given wide latitude in what they may play, similar to the freeform format but with the proviso that some kind of rock music is almost always played. It enjoyed the height of its popularity in the late 1960s and 1970s. The name for the format began being used circa 1968, when serious disc jockeys were playing "progressive 'music for the head ' " and discussing social issues in between records. During the late 1960s, as long-playing records began to supplant the single in popularity with rock audiences, progressive rock stations placed more emphasis on album tracks than did their AM counterparts. Throughout the 1970s, as FM stations moved to more structured formats, progressive rock evolved into album-oriented rock (AOR).

144-510: A Thanksgiving tradition on other underground/progressive stations. Many DJs at underground stations also chose to play entire sides of albums that contained multiple tracks, which could range from 20 to 30 minutes. At that time, these actions were considered very bold, so there was clearly a need for a radio format that could not only explore beyond the Top 40 , but be allowed to do so with the DJs leading

216-403: A compilation of songs created by any average listener of music. The songs on a mixtape generally relate to one another in some way, whether it be a conceptual theme or an overall sound. After the introduction of Compact discs, the term "Mixtape" began to apply to any personal compilation of songs on any given format. The sales of Compact Cassettes eventually began to decline in the 1990s, after

288-424: A current or former member of a musical group which is released under that artist's name only, even though some or all other band members may be involved. The solo album appeared as early as the late 1940s. A 1947 Billboard magazine article heralded " Margaret Whiting huddling with Capitol execs over her first solo album on which she will be backed by Frank De Vol ". There is no formal definition setting forth

360-561: A customer buys a whole album rather than just one or two songs from the artist. The song is not necessarily free nor is it available as a stand-alone download, adding also to the incentive to buy the complete album. In contrast to hidden tracks , bonus tracks are included on track listings and usually do not have a gap of silence between other album tracks. Bonus tracks on CD or vinyl albums are common in Japan for releases by European and North American artists; since importing international copies of

It now broadcasts on a normal 24-hour schedule from a new studio in the basement of the Lavin-Bernick Center for University Life on the Tulane campus. WTUL is volunteer-run, accepting DJs from across the Tulane and New Orleans community. WTUL releases an edition of its compilation CD Songs from

504-522: A single case, or a triple album containing three LPs or compact discs. Recording artists who have an extensive back catalogue may re-release several CDs in one single box with a unified design, often containing one or more albums (in this scenario, these releases can sometimes be referred to as a "two (or three)-fer"), or a compilation of previously unreleased recordings. These are known as box sets . Some musical artists have also released more than three compact discs or LP records of new recordings at once, in

576-433: A solo album for several reasons. A solo performer working with other members will typically have full creative control of the band, be able to hire and fire accompanists, and get the majority of the proceeds. The performer may be able to produce songs that differ widely from the sound of the band with which the performer has been associated, or that the group as a whole chose not to include in its own albums. Graham Nash of

648-414: A studio. However, the common understanding of a "live album" is one that was recorded at a concert with a public audience, even when the recording is overdubbed or multi-tracked. Concert or stage performances are recorded using remote recording techniques. Albums may be recorded at a single concert , or combine recordings made at multiple concerts. They may include applause, laughter and other noise from

720-430: A studio. Studios are built to absorb sound, eliminating reverberation , to assist in mixing different takes; other locations, such as concert venues and some "live rooms", have reverberation, which creates a "live" sound. Recordings, including live, may contain editing, sound effects, voice adjustments, etc. With modern recording technology , artists can be recorded in separate rooms or at separate times while listening to

792-660: A temporary location due to the renovation of the University Center) was damaged by the resulting flood waters. On December 15, 2005, the station began broadcasting again, using donated studio space on the mezzanine of the Rue de la Course coffeehouse in the Carrollton neighborhood of uptown New Orleans , about 10 blocks from the Tulane campus. The station kept its Internet broadcast running via donated bandwidth from CCRMA at Stanford University . The station continued

Promotional sampler albums are compilations. A tribute or cover album is a compilation of cover versions of songs or instrumental compositions. Its concept may involve various artists covering the songs of

936-516: A trend of shifting sales in the music industry , some observers feel that the early 21st century experienced the death of the album . An album may contain any number of tracks. In the United States, The Recording Academy 's rules for Grammy Awards state that an album must comprise a minimum total playing time of 15 minutes with at least five distinct tracks or a minimum total playing time of 30 minutes with no minimum track requirement. In

1008-430: A variety of genres. The station runs 24 hours. Tulane University students, and New Orleans local affiliates run the non-profit station. WTUL was established on March 14, 1959. It is the station which gave future mayor -turned TV news anchor -turned talk show host Jerry Springer his start. The yearly "Rock On Survival Marathon" fund raisers featuring live bands on the Tulane campus are a locally famous event. In spite of

1080-430: A way of promoting the album. Albums have been issued that are compilations of older tracks not originally released together, such as singles not originally found on albums, b-sides of singles, or unfinished " demo " recordings. Double albums during the seventies were sometimes sequenced for record changers . In the case of a two-record set, for example, sides 1 and 4 would be stamped on one record, and sides 2 and 3 on

1152-580: Is any vocal content. A track that has the same name as the album is called the title track. A bonus track (also known as a bonus cut or bonus) is a piece of music which has been included as an extra. This may be done as a marketing promotion, or for other reasons. It is not uncommon to include singles, B-sides , live recordings , and demo recordings as bonus tracks on re-issues of old albums, where those tracks were not originally included. Online music stores allow buyers to create their own albums by selecting songs themselves; bonus tracks may be included if

1224-555: Is not necessarily just in MP3 file format, in which higher quality formats such as FLAC and WAV can be used on storage media that MP3 albums reside on, such as CD-R-ROMs , hard drives , flash memory (e.g. thumbdrives , MP3 players , SD cards ), etc. The contents of the album are usually recorded in a studio or live in concert, though may be recorded in other locations, such as at home (as with JJ Cale's Okie , Beck's Odelay , David Gray's White Ladder , and others), in

1296-402: Is recorded on both the "A" and "B" side of the tape, with cassette being "turned" to play the other side of the album. Compact Cassettes were also a popular way for musicians to record " Demos " or "Demo Tapes" of their music to distribute to various record labels, in the hopes of acquiring a recording contract . Compact cassettes also saw the creation of mixtapes , which are tapes containing

1368-511: The FCC , broadcasters were slow to take advantage of the new airwaves available to them because their advertising revenues were generated primarily from existing AM broadcasting stations and because there were few FM radio receivers owned by the general public. This void created an opportunity for the disenchanted youth of the counterculture of the 1960s and their counterparts, Hippies and Flower Children , to express themselves by playing music that

1440-520: The iPod , US album sales dropped 54.6% from 2001 to 2009. The CD is a digital data storage device which permits digital recording technology to be used to record and play-back the recorded music. Most recently, the MP3 audio format has matured, revolutionizing the concept of digital storage. Early MP3 albums were essentially CD-rips created by early CD- ripping software, and sometimes real-time rips from cassettes and vinyl. The so-called "MP3 album"

1512-524: The 1970s. Appraising the concept in Christgau's Record Guide: Rock Albums of the Seventies (1981), Robert Christgau said most "are profit-taking recaps marred by sound and format inappropriate to phonographic reproduction (you can't put sights, smells, or fellowship on audio tape). But for Joe Cocker and Bette Midler and Bob-Dylan -in-the-arena, the form makes a compelling kind of sense." Among

1584-415: The 21st-century have mostly focused on CD and MP3 formats. The 8-track tape was the first tape format widely used alongside vinyl from 1965 until being phased out by 1983, being gradually supplanted by the cassette tape throughout the 1970s and early 1980s; the popularity of the cassette reached its peak during the late 1980s before sharply declining during the 1990s. The cassette had largely disappeared by

1656-443: The 25-minute mark. The album Dopesmoker by Sleep contains only a single track, but the composition is over 63 minutes long. There are no formal rules against artists such as Pinhead Gunpowder referring to their own releases under thirty minutes as "albums". If an album becomes too long to fit onto a single vinyl record or CD, it may be released as a double album where two vinyl LPs or compact discs are packaged together in

1800-496: The Hollies described his experience in developing a solo album as follows: "The thing that I go through that results in a solo album is an interesting process of collecting songs that can't be done, for whatever reason, by a lot of people". A solo album may also represent the departure of the performer from the group. A compilation album is a collection of material from various recording projects or various artists, assembled with

1872-494: The Long Playing record format in 1948, it was natural the term album would continue. Columbia expected that the record size distinction in 78s would continue, with classical music on 12" records and popular music on 10" records, and singles on 78s. Columbia's first popular 10" LP in fact was Frank Sinatra's first album, the four-record eight-song The Voice of Frank Sinatra , originally issued in 1946. RCA's introduction of

1944-614: The Psychedelic Era," a syndicated program heard on some non-commercial stations, recreates the format, but rarely includes any recordings made after 1970. Some of the spirit of progressive rock radio (albeit in a more mellow, "adult" form) can also be found in the adult album alternative format. Album An album is a collection of audio recordings (e.g., music ) issued on a medium such as compact disc (CD), vinyl (record), audio tape (like 8-track or cassette ), or digital . Albums of recorded sound were developed in

2016-591: The United Kingdom, the criteria for the UK Albums Chart is that a recording counts as an "album" if it either has more than four tracks or lasts more than 25 minutes. Sometimes shorter albums are referred to as mini-albums or EPs . Albums such as Tubular Bells , Amarok , and Hergest Ridge by Mike Oldfield , and Yes's Close to the Edge , include fewer than four tracks, but still surpass

2088-413: The album can be cheaper than buying a domestically released version, Japanese releases often feature bonus tracks to incentivize domestic purchase. Commercial sheet music is published in conjunction with the release of a new album (studio, compilation, soundtrack, etc.). A matching folio songbook is a compilation of the music notation of all the songs included in that particular album. It typically has

2160-526: The album's artwork on its cover and, in addition to sheet music, it includes photos of the artist. Most pop and rock releases come in standard Piano/Vocal/Guitar notation format (and occasionally Easy Piano / E-Z Play Today). Rock-oriented releases may also come in Guitar Recorded Versions edition, which are note-for-note transcriptions written directly from artist recordings. Vinyl LP records have two sides, each comprising one-half of

2232-511: The album. If a pop or rock album contained tracks released separately as commercial singles , they were conventionally placed in particular positions on the album. During the sixties, particularly in the UK, singles were generally released separately from albums. Today, many commercial albums of music tracks feature one or more singles, which are released separately to radio, TV or the Internet as

2304-479: The amount of participation a band member can solicit from other members of their band, and still have the album referred to as a solo album. One reviewer wrote that Ringo Starr 's third venture, Ringo , "[t]echnically... wasn't a solo album because all four Beatles appeared on it". Three of the four members of the Beatles released solo albums while the group was officially still together. A performer may record

2376-510: The audience, comments by the performers between pieces, improvisation, and so on. They may use multitrack recording direct from the stage sound system (rather than microphones placed among the audience), and can employ additional manipulation and effects during post-production to enhance the quality of the recording. Notable early live albums include the double album of Benny Goodman , The Famous 1938 Carnegie Hall Jazz Concert , released in 1950. Live double albums later became popular during

2448-406: The best selling live albums are Eric Clapton 's Unplugged (1992), selling over 26 million copies, Garth Brooks ' Double Live (1998), over 21 million copies, and Peter Frampton 's Frampton Comes Alive! (1976), over 11 million copies. In Rolling Stone ' s 500 Greatest Albums of All Time , 18 albums were live albums. A solo album , in popular music , is an album recorded by

2520-551: The early 1900s, the typical 10-inch disc could only hold about three minutes of sound per side, so almost all popular recordings were limited to around three minutes in length. Classical-music and spoken-word items generally were released on the longer 12-inch 78s, playing around 4–5 minutes per side. For example, in 1924, George Gershwin recorded a drastically shortened version of his new seventeen-minute composition Rhapsody in Blue with Paul Whiteman and His Orchestra. The recording

2592-456: The early 20th century as individual 78 rpm records (78s) collected in a bound book resembling a photo album ; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33 + 1 ⁄ 3   rpm . The album was the dominant form of recorded music expression and consumption from the mid-1960s to the early 21st century, a period known as the album era . Vinyl LPs are still issued, though album sales in

2664-506: The early nineteenth century. Later, collections of related 78s were bundled in book-like albums (one side of a 78 rpm record could hold only about 3.5 minutes of sound). When LP records were introduced, a collection of pieces or songs on a single record was called an "album"; the word was extended to other recording media such as compact disc, MiniDisc , compact audio cassette, 8-track tape and digital albums as they were introduced. An album (Latin albus , white), in ancient Rome,

2736-624: The field – as with early blues recordings, in prison, or with a mobile recording unit such as the Rolling Stones Mobile Studio . Most albums are studio albums —that is, they are recorded in a recording studio with equipment meant to give those overseeing the recording as much control as possible over the sound of the album. They minimize external noises and reverberations and have highly sensitive microphones and sound mixing equipment. Band members may record their parts in separate rooms or at separate times, listening to

2808-491: The first decade of the 2000s. Most albums are recorded in a studio , although they may also be recorded in a concert venue , at home, in the field, or a mix of places. The time frame for completely recording an album varies between a few hours to several years. This process usually requires several takes with different parts recorded separately, and then brought or " mixed " together. Recordings that are done in one take without overdubbing are termed "live", even when done in

2880-500: The form of a prototype. Compact Cassettes became especially popular during the 1980s after the advent of the Sony Walkman , which allowed the person to control what they listened to. The Walkman was convenient because of its size, the device could fit in most pockets and often came equipped with a clip for belts or pants. The compact cassette used double-sided magnetic tape to distribute music for commercial sale. The music

2952-480: The form of boxed sets, although in that case the work is still usually considered to be an album. Material (music or sounds) is stored on an album in sections termed tracks. A music track (often simply referred to as a track) is an individual song or instrumental recording. The term is particularly associated with popular music where separate tracks are known as album tracks; the term is also used for other formats such as EPs and singles . When vinyl records were

3024-499: The format was too unprofessional to serve a broad audience, believing that his underground stations were not achieving their potential (in reality, most of the reason for any ratings lagging was a lag in FM receiver adoption; McLendon's Buffalo station WPHD had the market's best ratings with its freeform program hosted by Jim Santella, but only in the evening hours where listeners had home receivers). Where once "progressive rock radio [was]

3096-487: The format's original sound, there may be no real examples of the specific progressive rock radio format in existence today on the FM dial. The closest thing to a progressive rock station may be the Deep Tracks channel on Sirius XM Satellite Radio , which plays some of the music originally heard on progressive rock radio, but without pronounced disc jockey personalities or the full feel of the original format. "Stuck in

3168-415: The front cover and liner notes on the back or inside cover. Most albums included three or four records, with two sides each, making six or eight compositions per album. By the mid-1930s, record companies had adopted the album format for classical music selections that were longer than the roughly eight minutes that fit on both sides of a classical 12" 78 rpm record. Initially the covers were plain, with

3240-1037: The higher-profile stations among these were owned by Metromedia . College progressive rock radio stations included WVBR in Ithaca, New York , WKNC in Raleigh, North Carolina , WBRU in Providence, Rhode Island , WRPI in Troy, New York , and WWUH in Hartford, Connecticut . Pioneering progressive rock radio disc jockey and program directors included Scott Muni in New York, Lee Arnold in Orlando, Tom Donahue in San Francisco, and Jim Santella in Buffalo. Over time (some much faster than others),

3312-508: The key media of ascendant rock culture", as writer Nelson George put it, by 1987, musician and author Robert Palmer would write, "The glory days of 'progressive' rock radio - when the disk jockey actually chose the records he played and creatively juxtaposed songs and styles - are long gone." While freeform stations are still around in the 2000s, such as New Jersey's WFMU , and for a while WXRC in Charlotte, North Carolina , recalled

3384-444: The large-city progressive rock stations usually lost DJ freedom and adopted the more structured and confined album-oriented rock (AOR) format in the late 1970s and 1980s, and then later the nostalgic classic rock format in the 1980s and 1990s, while the smaller stations sometimes turned to college rock or alternative rock . The trend had begun in the early 1970s as national station owners such as Gordon McLendon had decided that

3456-459: The low wattage, WTUL was occasionally picked up as far away as New York City in its early years due to the limited number of stations operating on the FM band. " Mother-in-Law " singer Ernie K-Doe was a DJ at WTUL for many years. WTUL went off the air on August 28, 2005, as Hurricane Katrina approached the New Orleans area. The Tulane campus building which housed the station (itself

3528-487: The mid-1960s to the late 1970s when the Compact Cassette format took over. The format is regarded as an obsolete technology, and was relatively unknown outside the United States, the United Kingdom, Canada and Australia. Stereo 8 was created in 1964 by a consortium led by Bill Lear of Lear Jet Corporation , along with Ampex , Ford Motor Company , General Motors , Motorola , and RCA Victor Records . It

3600-481: The name of the selection and performer in small type. In 1938, Columbia Records hired the first graphic designer in the business to design covers, others soon followed and colorful album covers cover became an important selling feature. By the later '30s, record companies began releasing albums of previously released recordings of popular music in albums organized by performer, singers or bands, or by type of music, boogie-woogie , for example. When Columbia introduced

3672-443: The other parts of the track with headphones to keep the timing right. In the 2000s, with the advent of digital recording , it became possible for musicians to record their part of a song in another studio in another part of the world, and send their contribution over digital channels to be included in the final product. Recordings that are done in one take without overdubbing or multi-tracking are termed "live", even when done in

3744-438: The other parts using headphones ; with each part recorded as a separate track . Album covers and liner notes are used, and sometimes additional information is provided, such as analysis of the recording, and lyrics or librettos . Historically, the term "album" was applied to a collection of various items housed in a book format. In musical usage, the word was used for collections of short pieces of printed music from

3816-414: The other. The user would stack the two records onto the spindle of an automatic record changer, with side 1 on the bottom and side 2 (on the other record) on top. Side 1 would automatically drop onto the turntable and be played. When finished, the tone arm's position would trigger a mechanism which moved the arm out of the way, dropped the record with side 2, and played it. When both records had been played,

3888-484: The paper cover in small type were the words "Record Album". Now records could be stored vertically with the record not touching the shelf, and the term was applied to the collection. In the early nineteenth century, "album" was occasionally used in the titles of some classical music sets, such as Robert Schumann 's Album for the Young Opus 68, a set of 43 short pieces. With the advent of 78 rpm records in

3960-406: The primary medium for audio recordings a track could be identified visually from the grooves and many album covers or sleeves included numbers for the tracks on each side. On a compact disc the track number is indexed so that a player can jump straight to the start of any track. On digital music stores such as iTunes the term song is often used interchangeably with track regardless of whether there

4032-432: The publishers of photograph albums. Single 78 rpm records were sold in a brown heavy paper sleeve with a large hole in the center so the record's label could be seen. The fragile records were stored on their sides. By the mid-1920s, photo album publishers sold collections of empty sleeves of heavier paper in bound volumes with stiff covers slightly larger than the 10" popular records. (Classical records measured 12".) On

4104-404: The record industry as a standard format for the "album". Apart from relatively minor refinements and the important later addition of stereophonic sound capability, it has remained the standard format for vinyl albums. The term "album" was extended to other recording media such as 8-track tape , cassette tape , compact disc , MiniDisc , and digital albums, as they were introduced. As part of

4176-452: The release and distribution Compact Discs . The 2010s saw a revival of Compact Cassettes by independent record labels and DIY musicians who preferred the format because of its difficulty to share over the internet . The compact disc format replaced both the vinyl record and the cassette as the standard for the commercial mass-market distribution of physical music albums. After the introduction of music downloading and MP3 players such as

4248-520: The rock market. Underground stations clearly disdained Top 40 music and made it a policy to avoid playing it. A dilemma grew because many underground artists were contractually obligated to release a certain amount of singles and FCC regulations required such songs to be 3 minutes long, or less. These "single versions" were often quite different than what was on the originating albums. Underground radio could liberally play what were referred to as "the album versions" of songs, no matter how long they were. By

4320-463: The same token, hugely popular and successful albums such as The Beatles ' Sgt. Pepper's Lonely Hearts Club Band and Arlo Guthrie 's Alice's Restaurant did not contain any singles. In fact, the actual song " Alice's Restaurant " is the entire Side A of its titular album, coming in at over 18 minutes, making it way over the 3-minute mandate, grew to fame in part because of persistent airplay from underground radio host Bob Fass , and later became

4392-448: The smaller 45 rpm format later in 1948 disrupted Columbia's expectations. By the mid-1950s, 45s dominated the singles market and 12" LPs dominated the album market and both 78s and 10" LPs were discontinued. In the 1950s albums of popular music were also issued on 45s, sold in small heavy paper-covered "gate-fold" albums with multiple discs in sleeves or in sleeves in small boxes. This format disappeared around 1960. Sinatra's "The Voice"

Record changers were used for many years of the LP era, but eventually fell out of use. 8-track tape (formally Stereo 8: commonly known as the eight-track cartridge, eight-track tape, or simply eight-track) is a magnetic tape sound recording technology popular in the United States from

4536-483: The way. This in turn led to established and new rock artists placing greater emphasis on long or experimental album tracks, knowing they would receive radio airplay. The progressive rock radio format should not be confused with the progressive rock music genre. While progressive rock music was certainly played on progressive rock radio stations, a number of other varieties of rock music were also played. Generally everything from early Beatles and early Dylan on forward

4608-1842: Was WNEW-FM in New York in the late 1960s, 1970s, and into the 1980s. For instance, Keith Emerson credited it for breaking Emerson, Lake & Palmer into the United States market. Other long-running, large-market examples included WMMR in Philadelphia (credited with helping to break Bruce Springsteen ), WBCN in Boston , WHFS in Washington, D.C. , WXRT in Chicago , WMMS in Cleveland , WEBN in Cincinnati , CJOM, WWWW and WABX in Detroit / Windsor , WZMF in Milwaukee , KQRS-FM in Minneapolis , WOWI in Norfolk , WORJ-FM in Orlando , KSHE in St. Louis , KDKB in Phoenix , KMET in Los Angeles , KSAN in San Francisco , KZAP and KSFM (102.5) in Sacramento , KZEW in Dallas, and KTIM in San Rafael . Many of

It was from this that in medieval and modern times, album came to denote a book of blank pages in which verses, autographs, sketches, photographs and the like are collected. This in turn led to the modern meaning of an album as a collection of audio recordings issued as a single item. The first audio albums were actually published by

4752-548: Was a further development of the similar Stereo-Pak four-track cartridge created by Earl "Madman" Muntz . A later quadraphonic version of the format was announced by RCA in April 1970 and first known as Quad-8, then later changed to just Q8. The Compact Cassette was a popular medium for distributing pre-recorded music from the early 1970s to the early 2000s. The first "Compact Cassette" was introduced by Philips in August 1963 in

4824-565: Was a good example on the East Coast. The progressive rock radio format grew out of the freeform radio format , and, sharing the key characteristic of disc jockeys having the freedom to play what they chose, has sometimes been referred to as "freeform rock radio" or "freeform progressive radio" or simply "FM rock radio". But as they evolved there were key differences between the freeform and progressive rock formats: The archetypal successful and influential progressive rock radio station

4896-476: Was fair game. Progressive rock radio was generally the only outlet for fringe rock genres such as space rock , jazz fusion , and quiet, acoustic-based folk rock and country rock (often played on weekend mornings). Progressive stations were also known for having " turntable hits ", songs by obscure artists that did not sell much and were not hits by any conventional measure, but which listeners kept calling up and requesting; Sweet Thursday 's " Gilbert Street "

4968-399: Was issued in 1952 on two extended play 45s, with two songs on each side, in both packagings. The 10-inch and 12-inch LP record (long play), or 33 + 1 ⁄ 3   rpm microgroove vinyl record, is a gramophone record format introduced by Columbia Records in 1948.
