The Beatles. I was 8 and a half when they played Ed Sullivan and totally took over AM radio. It was like nothing that has happened since. I went to bed with a small transistor radio under my pillow every night. Then Hendrix took me in a new direction when I was a little older. Then Captain Beefheart ruled my clique and I went to all his shows with the Magic Band. I saw Pink Floyd in 1972 in Carnegie Hall in 1972 @ age 16 and never missed another Floyd show in the NY metro area.
