Abbey Road is the eleventh studio album by the English rock band the Beatles. It is the last album the group started recording, although Let It Be was the last album completed before the band's break-up in April 1970. It was mostly recorded in April, July and August 1969, and was released on 26 September 1969 in the United Kingdom, and 1 October 1969 in the United States, reaching number one in both countries. A double A-side single from the album, "Something" / "Come Together" was released in October, which also topped the charts in the US. Abbey Road incorporates styles such as rock, pop, blues, singer-songwriter, and progressive rock, and makes prominent use of the Moog synthesizer and guitar played through a Leslie speaker unit.

By contrast, critics today view the album as one of the Beatles' best and rank it as one of the greatest albums of all time. George Harrison's two songs on the album, "Something" and "Here Comes the Sun", have been regarded as among the best he wrote for the group. The album's cover, featuring the group walking across a zebra crossing outside Abbey Road Studios, has become one of the most famous and imitated in the history of recorded music. Background After the recording sessions for the proposed Get Back album, Paul McCartney suggested to music producer George Martin that the group get together and make an album "the way we used to do it", free of the conflict that had begun during sessions for The Beatles (also known as the "White Album"). Martin agreed, but on the strict condition that all the group – particularly John Lennon – allow him to
