An English rock band formed in London in 1965. Gaining a following as a psychedelic band, they were distinguished for their extended compositions, sonic experimentation, philosophical lyrics and elaborate live shows, and became a leading band of the progressive rock genre. They are one of the most commercially successful and influential groups in popular music history.
Pink Floyd were founded by students Syd Barrett (guitar and lead vocals), Nick Mason (drums), Roger Waters (bass and vocals), and Richard Wright (keyboards and vocals). Under Barrett's leadership, they released two charting singles and a successful debut album, The Piper at the Gates of Dawn (1967). Guitarist and vocalist David Gilmour joined in December 1967; Barrett left in April 1968 due to deteriorating mental health. Waters became their primary lyricist and thematic leader, devising the concepts behind the albums The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), The Wall (1979) and The Final Cut (1983).
