Abbey Road is the eleventh studio album by the English rock band the Beatles, released on 26 September 1969 by Apple Records. The recording sessions for the album were the last in which all four Beatles participated. Although Let It Be was the final album that the Beatles completed before the band's dissolution in April 1970, most of the album had been recorded before the Abbey Road sessions began. A double A-side single from the album, "Something"/"Come Together", released in October, topped the Billboard chart in the US.
Abbey Road is a rock album that incorporates genres such as blues, pop and progressive rock, and it makes prominent use of the Moog synthesizer and the Leslie speaker. Side two contains a medley of song fragments edited together to form a single piece. The album was recorded amid a more collegial atmosphere than the Get Back/Let It Be sessions earlier in the year, but there were still frequent disagreements within the band, particularly over Paul McCartney's song "Maxwell's Silver Hammer". John Lennon had privately left the group by the time the album was released and McCartney publicly quit the following year.
