Jimmy Reed

Mathis James "Jimmy" Reed (September 6, 1925 – August 29, 1976) was an American blues musician and songwriter, notable for bringing his distinctive style of blues to mainstream audiences. Reed was a major player in the field of electric blues, as opposed to the more acoustic-based sound of many of his contemporaries. His lazy, slack-jawed singing, piercing harmonica and hypnotic guitar patterns were one of the blues' most easily identifiable sounds in the 1950s and 1960s, and had a significant impact on many rock and roll artists who followed, such as Elvis Presley, Billy Gibbons and the Rolling Stones.
