Pink Floyd are an English rock band who initially earned recognition for their psychedelic or space rock music, and, as they evolved, for their progressive rock music. They are known for philosophical lyrics, sonic experimentation, innovative cover art, and elaborate live shows. One of rock music's most successful acts, the group have sold over 200 million albums worldwide including 74.5 million albums in the United States alone.

Pink Floyd had moderate mainstream success and were one of the most popular bands in the London underground music scene in the late 1960s as a psychedelic band led by Syd Barrett; however, Barrett's erratic behaviour eventually forced his colleagues to replace him with guitarist and singer David Gilmour. After Barrett's departure, singer and bass player Roger Waters gradually became the dominant and driving force in the group in the late-1970s, until his eventual departure from the group in 1985. The band recorded several albums, achieving worldwide success with The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), and The Wall (1979). In 1985, Waters declared Pink Floyd "a spent force", but the remaining members, led by Gilmour, continued recording and touring under the name Pink Floyd. Although they were unsuccessfully sued by Waters for rights to the name, they again enjoyed worldwide success with A Momentary Lapse of Reason (1987) and The Division Bell (1994). Eventually they reached a settlement out of court with Waters allowing them use of the name. Waters performed with the band for the first time in 24 years on 2 July 2005 at the London Live 8 concert

"I'm full of dust and guitars."
Syd Barrett

“It is with the utmost respect to Pink Floyd that we took the challenge.”
Roger Waters

"I've simply tried to capture the elements that I think give a picture of what I thought was happening at any one time, and to try to be honest about both the triumphs and the complete shambles that make up a band's existence.”
Nick Mason

"Blues, spirituals, and folk tales recounted from mouth to mouth . . . all these formed the channels through which the racial wisdom flowed.”
Rick Wright
