“One of the most sampled artists of our time, his music served as the soundtrack for some of our most poignant moments in history,” his family said.

Born in Holly Springs, Mississippi, Johnson moved to Chicago’s South Side as a teenager and started playing blues guitar. He was named a Blues Hall of Fame inductee in 2019.

Johnson left the music business for a time in the 1980s and founded Solomon’s Fishery, a fried fish restaurant which later became a largely Chicago-area chain.
