Paul Butterfield, American singer and harmonica player (died 1987)

Paul Vaughn Butterfield was an American blues harmonica player, singer, and bandleader. After early training as a classical flautist, he developed an interest in blues harmonica. He explored the blues scene in his native Chicago, where he met Muddy Waters and other blues greats, who provided encouragement and opportunities for him to join in jam sessions. He soon began performing with fellow blues enthusiasts Nick Gravenites and Elvin Bishop.
