The Beatles' groundbreaking seventh album, Revolver, turns 50 years old this week. To celebrate, we'll be taking a look back at the album's sweeping impact as a musical document and on the band's career trajectory.

This is the moment when the Beatles shifted from their earlier life as a touring group toward a sustained period of studio innovation, and they pushed hard against the edges of that new frontier -- incorporating tape loops, exotic instrumentation and sound effects, coupled with a broadening of their chosen subject matter that was just as thrilling. Even the cover art was a wonder of innovative depth, an image that mirrored the album's sense of fizzy complexity.

Revolver, in short, changed everything – and not just for the Beatles. It set a new standard in pop music that pushed everyone – including John Lennon, Paul McCartney, George Harrison and Ringo Starr – to new creative heights.
