Sonny Boy Williamson II — born Aleck 'Rice' Miller, though he adopted the more famous name of a rival harmonica player — spent years broadcasting on the King Biscuit Time radio show before recording his first single, 'Eyesight to the Blind,' in 1951. His fluid, conversational harmonica phrasing and sly, world-weary vocal delivery made him one of the most influential blues harp players of the postwar era, and he later toured the UK and jammed with young British blues-rock bands. He died in 1965, not long after those European tours introduced his playing to a new generation of rock musicians.
