The day the universe changed

record-player-150292__340 50 years ago this week, The Beatles served notice that a new day had dawned in popular music.

Revolver, their seventh studio album, was such a game changer the public seemed initially stunned by it. (The musician community certainly was, when the band's latest offering forced them to confront the artistic gap between The Beatles and just about everyone else.) The LP sold millions—as any Beatles’ record did—but less than Rubber Soul eight months earlier.

Record buyers may have been a tad distracted by John Lennon's remarks that The Beatles were “more popular than Jesus,” which produced mass burnings of Beatles’ records in America's Bible Belt days before the release of Revolver. (Oops.)

But eventually the new album got the attention it deserved, due in large part to its unusual instrumentation (including the use of clavichord, vibraphone, tack piano, tabla, tambura, sitar, and string octet) and especially its novel production effects (including backwards recording, tape loops, variable tape speeds, and automatic double tracking). All contributed to a sonic masterpiece, as demonstrated by the other-worldly "Tomorrow Never Knows.”
