The Beatles may have released Let It Be last, but their final work as a band was Abbey Road. It's definitive proof that the band broke up at the absolute height of their powers. Recorded in the summer of 1969 after the torturous Let It Be sessions, The Beatles knew that Abbey Road was going to be their last effort, so they put aside their differences to craft a masterpiece. "Something" may well be George Harrison's single greatest song, while Lennon's "Come Together" and McCartney's "Oh! Darling" are near-perfect compositions. Ringo even delivered a winner with "Octopus's Garden," one of the few Beatles songs he wrote by himself. The best part of the LP, however, is side two - a 16-minute suite of songs that seamlessly flow together. Who knows what would have happened had they stuck together for a few more albums.
