In the world of musical theatre, there is a separate and distinct form of concept album known as the album musical, in which the performers are playing characters in a story, a type of recording which encompasses such "rock operas" as The Who's Tommy and The Wall by Pink Floyd.
Another difficulty in classifying whether a given album qualifies as a concept album arises from the fact that both musicians and their listeners, through the rock era, increasingly viewed the record album as a unified art form, not simply a collection of songs. Songs on many albums may have a certain sense of cohesion even if there is no unifying lyrical theme or narrative structure. That sense of cohesion may be imposed simply by the particular lyrical or musical concerns of a composer or group of composers at the time a record was recorded. Thus, many albums that cannot genuinely be labelled concept albums in a strict sense get so designated by their fans. The album OK Computer by Radiohead is an example of this tendency. In this case, there was no intention by the performers to produce an actual concept album (although proponents of the view that it is one have pointed to apparent hints of a circular narrative in its lyrics, as an example of an apparent narrative). Some albums without any single theme or narrative structure may nonetheless have a deliberate structure in which the order in which the songs are heard expresses a particular artistic intention. Such an album, or other collection of songs, may be best viewed as a song cycle, a broader notion, with roots in classical music, that may encompass many concept albums.
In folk music, early examples included Woody Guthrie's 1940 debut album Dust Bowl Ballads i and Merle Travis's 1947 box set Folk Songs of the Hills, in which each song is introduced by a short narrative. In the late '40s, Kansas City pianist Pete Johnson recorded the album Pete's House Warmin', in which he starts out playing alone, supposedly in new empty house, and is joined there by J. C. Higginbotham, J.C. Heard, and other Kansas City players. Each has a solo backed by Pete and then the whole group plays a jam session together.
Frank Sinatra released many thematically programmed albums of the 1950s for Capitol Records starting with the ten-inch 33s Songs for Young Lovers and Swing Easy. Perhaps the first full Sinatra concept album example is In the Wee Small Hours from 1955, where the songs – all ballads – were specifically recorded for the album, and organized around a central mood of late-night isolation and aching lost love, with the album cover strikingly reinforcing that theme.
However, notion of a concept album did not really gel at that point, and was not widely imitated, aside from occasional examples such as country singer Marty Robbins' Gunfighter Ballads and Trail Songs from 1959, or Ray Charles's The Genius Hits the Road (1960), where each song references one of the United States ("Georgia on My Mind", "Mississippi Mud", et cetera). Also released that year, Johnny Cash's Ride This Train chronicled tales of Americana, woven together with narrative by Cash and train sounds. Each track begins with "Ride this train to ..." and tells the story of that city.
In 1966, several rock releases were arguably concept albums in the sense that they presented a set of thematically-linked songs - and they also instigated other rock artists to consider using the album format in a similar fashion: The Beach Boys' Pet Sounds was a masterful musical portrayal of Brian Wilson's state of mind at the time (and a major inspiration to Paul McCartney). Although it has a unified theme in its emotional content, the writers (Brian Wilson and Tony Asher) have said continuously that it was not necessarily intended to be a narrative. However, later in 1966, Brian Wilson had begun work on the Smile album, which was intended as a narrative. The album was scrapped before completion, only to be revived in the 2000s. The Mothers of Invention's sardonic farce about rock music and America as a whole, Freak Out!; and Face to Face by The Kinks, the first collection of Ray Davies's idiosyncratic character studies of ordinary people. However, none of these attracted a wide commercial audience.
This all changed with the Beatles' celebrated album Sgt. Pepper's Lonely Hearts Club Band in June 1967. With the release of Sgt. Pepper, the notion of the concept album came to the forefront of the popular and critical mind, with the earlier prototypes and examples from classic pop and other genres sometimes forgotten. The phrase entered the popular lexicon, and a "concept album" - the term became imbued with the notion of artistic purpose - was inherently considered to be more creative or worthy of attention than a mere collection of new songs. This perception of course related to the intent of the artist rather than the specific content.
In fact, as pointed out by many critics since its original reception, Sgt. Pepper is a concept album only by some definitions of the term. There was, at some stage during the making of the album an attempt to relate the material to firstly the idea of aging, then as an obscure radio play about the life of an ex-army bandsman and his shortcomings. These concepts were lost in the final production. While debate exists over the extent to which Sgt. Pepper qualifies as a true concept album, there is no doubt that its reputation as such helped inspire other artists to produce concept albums of their own, and inspired the public to anticipate them. Lennon and McCartney distanced themselves from the "concept album" tag as applied to that album.
The Who Sell Out followed with its concept of a pirate radio broadcast. Within the record, joke commercials recorded by the band and actual jingles from recently outlawed pirate radio station Wonderful Radio London were interspersed between the songs, ranging from pop songs to hard rock and psychedelic rock, culminating with a mini-opera titled "Rael".
The album S.F. Sorrow (released in December 1968) by British group the Pretty Things is generally considered to be among the first creatively successful rock concept albums - in that each song is part of an overarching unified concept – the life story of the main character, Sebastian Sorrow,
Released in April 1969, was the rock opera Tommy composed by Pete Townshend and performed by The Who. This acclaimed work was presented over two discs (still unusual in those days) and it took the idea of thematically based albums to a much higher appreciation by both critics and the public. It was also the first story-based concept album of the rock era (as distinct from the song-cycle style album) to enjoy commercial success. The Who went on to further explorations of the concept album format with their follow-up project Lifehouse, which was abandoned before completion, and with their 1973 rock opera, Quadrophenia.
Five months after the release of Tommy, The Kinks released another concept album Arthur (Or the Decline and Fall of the British Empire) (September 1969), written by Ray Davies, considered by some a Rock Opera but originally conceived as the score for a proposed but never realised BBC television drama. It was the first of several concept albums released by the band through the first few years of the 1970s. These were: Lola versus Powerman and the Moneygoround, Part One (1970), Muswell Hillbillies (1971), Preservation: Act 1 (1973), Preservation: Act 2 (1974), Soap Opera (1975) and Schoolboys in Disgrace (1976).
Though the progressive rock genre was beginning to decrease its popularity, concept albums had become a medium that continued. The progressive bands that were still around were still having major successes with concept albums. Styx continued to have multiplatinum albums with their 1981 release Paradise Theater (a concept album about a decaying theater in Chicago which became a metaphor for childhood and American culture) and 1983's Kilroy Was Here (a science fiction rock opera about a future where moralists imprison rockers). Blue Öyster Cult released the album Imaginos in 1988, which included new versions of the songs Astronomy and Subhuman (retitled Blue Öyster Cult) and seven new songs, including one on which Joe Satriani played lead guitar.
80's metal bands released albums like Queensrÿche's Operation: Mindcrime; which tells a story of a young man, Nikki, awoken from a coma suddenly remembering work done as a political assassin, then falling in love with a nun, mixing around with heroin, seeking help, then being ordered to assassinate his love, (the story is very similar to La Femme Nikita) and Iron Maiden's Seventh Son of a Seventh Son; which follows the folklore and myths of a seventh son of a seventh son having mystical powers, such as being clairvoyant, enjoyed major successes in the 80s, as did W.A.S.P.'s The Crimson Idol.
The eighties also brought back an earlier form of the concept genre—albums with unifying themes, not necessarily coherent stories. An example is Journey's Escape in which all of the songs had to do with rebellion and escaping from one's present situation.
The jam band Phish recorded The Man Who Stepped Into Yesterday in 1987, chronicling the adventures of Colonel Forbin through the fictional world of Gamehendge. The album was never officially released, but was completed and has circulated heavily by fans, both as the studio recording and as live performances.

Irish rock band U2 released Achtung Baby in 1991 which, along with the Zoo TV tour that followed; expounded on the supposedly corrupting effects of television and the resulting cultural decadence of the time. This theme is quite well expressed in the video for the song "Even Better Than The Real Thing" from the album.
Rock band Coheed and Cambria's albums follow a story entitled The Amory Wars, a science-fiction story written by the band frontman Claudio Sanchez. The story also extends into the comic book and graphic novel realm. There fifth, unreleased album will be a prequel to the series, but other than that not much is known about the prequel album.
Concept albums are often among metal bands inspired by mythology and fantasy fiction. Examples of that kind are Blind Guardian's Nightfall in Middle-Earth, based on J. R. R. Tolkien's The Silmarillion; Therion's Secret of the Runes and Manowar's Gods of War, both based on Norse mythology; and others. All albums by Rhapsody of Fire, Avantasia and Bal-Sagoth feature continuous scenario in their lyrics.

Eventually, due to his criminal behaviour, Whatsername dumps Jimmy, who "commits suicide" and becomes Jesus of Suburbia again. After ditching his alter-ego, J.O.S. returns to his suburbial town.
Another progressive metal band, Protest the Hero, released a concept album entitled Kezia in 2005, telling the story of an eponymously-named woman who is sentenced to execution for ambiguous reasons. The album is broken up into three main sections which tell the same story from the perspectives of three different characters, as well as a final section consisting of a single song. The band's following album, Fortress, while less narrative, continues this pattern of three separate movements.
Symphonic-Progressive group, Spock's Beard, released their two-disced concept album, Snow, in 2002.

The Mars Volta, an experimental rock band, is notable for their concept albums, the majority of them carried by a narrative (such as their debut album 'Deloused in the Comatorium', which follows the journey through the mind of a man in a coma caused by a suicide attempt). However, it could be argued that, according to the criteria, that their album ' Amputechture' is not strictly a concept album, due to the lack of a narrative.

As a recording genre, the album musical predates the currently held definition of a concept album, dating back to the era of 78-rpm records with such original works as Gordon Jenkins' Manhattan Tower (1946) and The Letter (1959) starring Judy Garland. The primary difference is that on most concept albums, the performers or bands are singing as themselves, whereas on an album musical, the performers are playing characters in a story. On most Judy Garland albums, for example, Judy sings as herself, but on The Letter, she is playing a character.
