Abbey Road — The Beatles (1969)

Recorded amid the Beatles’ fracturing relationships in summer 1969, Abbey Road stands as their final recorded masterpiece. Its 17-minute Side 2 medley—widely hailed as rock’s greatest sustained sequence—generated 31 million worldwide sales, a figure 70% higher than #6's sales total. While Hendrix exploded convention, the Beatles here achieved flawless cohesion, with 'Something' and 'Here Comes the Sun' illustrating a maturity that surpasses the experimental looseness of #8. It’s a bittersweet triumph, forged from tension into timeless harmony.
