Pink Floyd were formed in 1965, soon after Syd Barrett joined The Tea Set, a group that consisted of architecture students Nick Mason, Roger Waters, Richard Wright and, briefly, Bob Klose. The group were a popular fixture on London's underground music scene, and under Barrett's leadership released two charting singles, "Arnold Layne" and "See Emily Play", and a commercially and critically successful album, The Piper at the Gates of Dawn. The erratic behaviour of Barrett prompted his colleagues to add guitarist and singer David Gilmour to the line-up. Following Barrett's departure, bass player and singer Roger Waters became the lyricist and dominant figure in the band, which thereafter achieved worldwide critical and commercial success with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals, and rock opera The Wall.
Wright left the band in 1979, and Waters in 1985, but Gilmour and Mason (joined by Wright) continued recording and touring under the name Pink Floyd. Waters used legal means to try to keep them from using the name, declaring Pink Floyd a spent force, but the parties reached an out-of-court settlement allowing Gilmour, Mason and Wright to continue as Pink Floyd. The band again enjoyed worldwide success with A Momentary Lapse of Reason (1987) and The Division Bell (1994), and Waters continued as a solo musician, releasing three studio albums. Although for some years relations between Waters and the remaining three members were sour, the band reformed for what would be a final one-off performance at Live 8. Founder member Syd Barrett died on 7 July 2006, aged 60, at his home in Cambridgeshire; then just over two years later, on 15 September 2008, Richard Wright died of cancer, aged 65.
