Little Walter
From Wikipedia:
Music journalist Bill Dahl described Little Walter as "king of all post-war blues harpists", who "took the humble mouth organ in dazzling amplified directions that were unimaginable prior to his ascendancy."[3] His legacy has been enormous: he is widely credited by blues historians as the artist primarily responsible for establishing the standard vocabulary for modern blues and blues rock harmonica players.[2][3] His influence can be heard in varying degrees in virtually every modern blues harp player who came along in his wake, from blues greats such as Junior Wells, James Cotton, George "Harmonica" Smith, Carey Bell, and Big Walter Horton, through modern-day masters Sugar Blue, Billy Branch, Kim Wilson, Rod Piazza, William Clarke, and Charlie Musselwhite, in addition to blues-rock crossover artists such as Paul Butterfield and John Popper of the band Blues Traveler.
