                          Beatles
The Beatles are, to many, the greatest rock group ever.  The Fab Four (John Lennon, Paul McCartney, Ringo Starr, and George Harrison) were the leaders of the British Invasion that swept across America in the early sixties.  Their early music is pure Pop, built on the doo wop of the fifties, while later they embraced the more open musical stylings of the sixties counter- culture with albums like "Sgt. Pepper's Lonely Hearts Club" and "Magical Mystery Tour."
