May 17, 1966 is the day the barn doors blew open in rock and roll.

Only a couple of months earlier, The Beatles had released RUBBER SOUL, an eclectic collection of personal songs by John, Paul, George, and Ringo that featured radically different instrumentation and subject matter from anything they had released previously.  Fifty-five years on, it may be that RUBBER SOUL is the greatest of all Beatles records in that it crystallized a moment and influenced the direction of popular music for years to come.
