Pink Floyd were one of the most influential rock bands in popular history. Forming in London in 1965, the band were highly distinguished for their extended compositions, philosophical lyrics, and sonic exploration.
Pink Floyd consisted of Syd Barrett (guitar and lead vocals), Nick Mason (drums), Roger Waters (bass and vocals), and Richard Wright (keyboards and vocals). David Gilmour joined the band in 1967, while Barrett left in '68 due to his impending schizophrenia and deteriorating mental health.
Gilmour became their lead guitarist and prominent singer while Waters became their lyricist and thematic leader, devising the concepts for such innovating concept albums such as The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), The Wall (1979) and The Final Cut (1983). By 2013, Pink Floyd sold more than 250 million records worldwide, with The Dark Side of the Moon and The Wall being two of the best-selling albums of all time.
