Harmonica Blues
Pioneered by the likes of Sonny Boy Williamson II, Lazy Lester and Jimmy Reed -- then carried into the later part of the century by Little Walter and Junior Wells -- Harmonica Blues centers around the blues "harp," or harmonica. Little Walter developed the style's electric sound in Chicago, while Slim Harpo played a neck harp in Louisiana at the same time. In later years, artists like Paul Butterfield and Bob Dylan incorporated harmonica into folk, rock, and blues revival.
