Little Sonny (born Aaron Willis; October 6, 1932, in Greensboro, Alabama) is an American electric blues harmonica player, singer and songwriter.^[1] His early mentor and inspiration was Sonny Boy Williamson II. Nevertheless, Little Sonny stated that his nickname was originated by his mother: “[She] called me ‘Sonny boy’ from the time I can remember.” He has released eight albums, including three for a subsidiary of Stax Records. His 1973 release, Hard Goin’ Up, reached the Top 50 in the Billboard R&B chart.

Willis was born in 1932 and raised solely by his mother. He relocated to Detroit in 1953. He had no real interest in music, he said, “But then I saw Sonny Boy Williamson II.” Willis was “spellbound at the way he played. After the show I went home and practiced for hours. Every day after that I would practice until I got the sound I wanted.” His daytime job was working in a used car lot.
