Pink Floyd were an English rock band who in the 1960s earned recognition for their psychedelic and space rock music, and in the 1970s, as they evolved, for their progressive rock music. After original singer Syd 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.
