The Beatles

general acclaim. Allmusic considers it "a fitting swan song for the group" containing "some of the greatest harmonies to be heard on any rock record". MacDonald calls it "erratic and often hollow": "Had it not been for McCartney's input as designer of the Long Medley... Abbey Road would lack the semblance of unity and coherence that makes it appear better than it is." Martin singled it out as his personal favourite of all the band's albums; Lennon said it was "competent" but had "no life in it", calling "Maxwell's Silver Hammer" "more of Paul's granny music". Recording engineer Geoff Emerick noted that the replacement of the studio's valve mixing console with a transistorised one produced a less punchy sound, leaving the group frustrated at the thinner tone and lack of impact. For the still uncompleted Get Back album, the final new Beatles song,
Harrison's "I Me Mine" was recorded on 3 January 1970. Lennon, in Denmark at the time, did not participate. To complete the album, now retitled Let It Be, in March Klein gave the Get Back session tapes to American producer Phil Spector. Known for his Wall of Sound approach, Spector had recently produced Lennon's solo single "Instant Karma!" In addition to remixing the Get Back material, Spector edited, spliced and overdubbed several of the recordings that had been intended as "live". McCartney was unhappy with Spector's treatment of the material and particularly dissatisfied with the producer's orchestration of "The Long and Winding Road", which involved a choir and thirty-four-piece instrumental ensemble. He unsuccessfully attempted to halt the release of Spector's version. McCartney publicly announced his departure from the band on 10 April, a week before the release of his first, self-titled solo album. Pre-release copies of McCartney's record included a press statement with a self-written interview, explaining the end of his involvement with the Beatles and his hopes for the future. On 8 May, the Spector-produced Let It Be was released. The accompanying single, "The Long and Winding Road", was the band's last; it was released in the United States, but not Britain. The Let It Be documentary film followed later in the month; at the Academy Award ceremony the next year, it would win the Oscar for Best Original Song Score. The Sunday Telegraph called it "a very bad film and a touching one ... about the breaking apart of this reassuring, geometrically perfect, once apparently ageless family of siblings."
