When the Beatles' music was introduced to CD, there was a need to wrangle all of the songs that didn’t appear on their original studio albums. Past Masters Volumes 1 and 2 solved this problem by collecting all of these tracks onto 2 CDs (or any other physical format). Present here on Volume 2 are all of the tracks not present on their original British studio albums and the US Capitol-generated Magical Mystery Tour LP between December 1965 and 1970, showcasing their continuing shift to a psychedelic sound in 1967 before returning to their older, more traditional pop rock style at the end of the decade.
