Yes are an English rock band who achieved success with their progressive, art, and symphonic style of rock music. They are distinguished by their use of mystical and cosmic lyrics, live stage sets and lengthy compositions, often with complex instrumental and vocal arrangements. The band's current line-up since February 2012 consists of singer Jon Davison, guitarist Steve Howe, bass guitarist Chris Squire, keyboardist Geoff Downes, and drummer Alan White.

Squire formed Yes in 1968 with singer Jon Anderson. Squire and guitarist Peter Banks had played together in The Syn and then Mabel Greer's Toyshop. Anderson and later drummer Bill Bruford joined a line-up of Mabel Greer's Toyshop, which evolved into Yes. Keyboardist Tony Kaye completed the first Yes line-up. Their early sets were a mix of original material and cover versions.
