Revolver is the seventh studio album by the English rock band the Beatles. Released on 5 August 1966, it was the Beatles' final recording project before their retirement as live performers and marked the group's most overt use of studio technology up to that time, building on the advances of their late 1965 release Rubber Soul. 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\". The album was reduced to eleven songs by Capitol Records in North America, where three of its tracks instead appeared on the June 1966 release Yesterday and Today.
