It was 53 years ago today (December 6th, 1965) that the Beatles released their groundbreaking sixth album, Rubber Soul. Also released in conjunction to the album was the band's first official "double A-sided" single, "We Can Work It Out" backed with "Day Tripper. Rubber Soul featured a staring of instant classics, including "Michelle" — which scored the band the 1967 Grammy for Song Of The Year despite it never being released by the band as a single — "In My Life," "Drive My Car," "Nowhere Man," "Girl," "I'm Looking Through You," and "Norwegian Wood (This Bird Has Flown)"– for which George Harrison is often credited for introducing world music into rock by contributing the song's signature sitar part.

In the U.S. "Drive My Car," "Nowhere Man," the John LennonPaul McCartneyRingo Starr-written "What Goes On," and "If I Needed Someone" were left off Rubber Soul and replaced with the Help! holdovers "I've Just Seen A Face" and "It's Only Love." Rubber Soul marks the first time an outtake from a prior album was included on a new project, with "Wait" originally recorded during the previous spring's Help! sessions but left unissued.

Much the same way Paul McCartney credits the Beach Boys' Pet Sounds as being the inspiration for Sgt. Pepper, Brian Wilson credits Rubber Soul for inspiring Pet Sounds. Rubber Soul was the final album to feature Norman Smith as the Beatles' engineer. He was promoted at EMI Records to producer status and went on to work with Pink Floyd. Save for a few instances, Geoff Emerick went on to be the group's primary engineer until their split.

The album is unique for several reasons; Paul McCartney played slide guitar on "Drive My Car," Ringo Starr made his keyboard debut playing the organ on "I'm Looking Through You," and the album was the first to feature McCartney playing his solid-bodied Rickenbacker 4001 bass, rather than his signature Hofner "violin" bass.

On January 8th, 1966 Rubber Soul hit Number One on the Billboard 200 albums chart, holding down the top spot for six weeks. That same day, "We Can Work It Out" knocked Simon & Garfunkel's "The Sound Of Silence" out from Number One for the first of three weeks on the Billboard Hot 100. "Day Tripper" peaked at Number Five — marking the group's 26th Top 40 hit in only two years.

Paul McCartney recalled how the band came to title the album Rubber Soul: ["The title Rubber Soul was, kind of 'Hey man, it's got soul — 'lotta soul, 'lotta soul, that music' — it was a spoof on that, y'know, seemed nice and amusing, very us — y'know, very whacky."] SOUNDCUE (:10 OC: . . . very whacky)

Shortly before his 2016 death, George Martin touched upon how as the Beatles gradually lost interest in live performance, their creative life in the studio grew by leaps and bounds: ["Oh yeah, they were becoming quite original. The thing is, though, they were eternally curious. They wanted to find new ways of doing what they were doing — new harmonies, new endings of songs, and that kind of thing. They would always want to look beyond the horizon."] SOUNDCUE (:15 OC: . . . beyond the horizon)

During the Beatles' final tour in 1966 they only included three Rubber Soul-era songs in their setlist — "Nowhere Man," "If I Needed Someone," and "Day Tripper."

Over the years, the songs of Rubber Soul have lived on through the solo Beatles concerts, with George Harrison performing "If I Needed Someone" during his 1991 tour of Japan; Ringo Starr frequently includes "What Goes On" in his All Starr Band shows; and Paul McCartney has tackled "Drive My Car," "You Won't See Me," "Michelle," "I've Just Seen A Face," "I'm Looking Through You," "The Word," "We Can Work It Out," and "Day Tripper" in his various world tours.
