Revolver is the seventh studio album by The Beatles. Released on 5 August 1966, it was the Beatles' final recording project before their retirement as live performers, and marked a progression on their 1965 release Rubber Soul in terms of the group's readiness to experiment in the recording studio. The album's diverse sounds include tape loops and backwards recordings on the psychedelic "Tomorrow Never Knows", a classical string octet on "Eleanor Rigby", and Indian-music backing on "Love You To".
