If the Beatles’ 10-year career could be broken up into two distinct acts, the dividing line might be Rubber Soul.

Released on Dec. 3, 1965, it marked an undeniable musical shift for the foursome, to the point where everything they released after it would only make sense if one had heard Rubber Soul. In John Lennon’s words from 1965: “You don’t know us now if you don’t know Rubber Soul.”

The Beatles’ sixth studio album featured much more expressive arrangements, maturer lyricism — “You can’t be singing 15-year-old songs at 20 because you don’t think 15-year-old thoughts at 20,” Paul McCartney explained to Newsweek back then — and wider use of instrumentation that had not been explored before by the Beatles or, for that matter, anyone else. Not for the first time and not for the last, the Beatles set an entirely new industry precedent.

Below, we’ve rounded up 15 such people, each of whom have specifically pointed to Rubber Soul as an album that shaped their thoughts on what music could sound like.
