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. 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. The album was recorded in a more collegial atmosphere than the Get Back / Let It Be sessions earlier in the year, but there were still significant confrontations within the band, particularly over Paul McCartney's song "Maxwell's Silver Hammer", and John Lennon did not perform on several tracks. By the time the album was released Lennon had left the group, though this was not publicly announced until McCartney also quit the following year. The album features “Come Together”, “Here Comes The Sun”, and “Something”.
