Pink Floyd

British psychedelic rock group, formed in 1965. The original members were Syd Barrett (1946–2006), Roger Waters (1944– ), Richard Wright (1945– ), and Nick Mason (1945– ). Dave Gilmour (1944– ) joined the band in 1968. Their albums include The Dark Side of the Moon (1973) and The Wall (1979).

Their debut album was Piper at the Gates of Dawn (1967). This was followed by, among others, Relics (1971), Wish You Were Here (1975), Animals (1977), and The Final Cut (1983). A comeback album The Division Bell (1994) was followed by the live album P.U.L.S.E. (1995).

Barrett left the band in 1968 and Wright in 1979, and from 1986 Gilmour and Mason used the name Pink Floyd in collaborations without Waters, leading to years of legal wrangles over their right to do so.
