Willie Dixon

William James "Willie" Dixon (July 1, 1915 – January 29, 1992) was an American blues musician, vocalist, songwriter, arranger and record producer. A Grammy Award winner who was proficient on both the upright bass and the guitar and as a vocalist, Dixon is perhaps best known as one of the most prolific songwriters of his time. Next to Muddy Waters, Dixon is recognized as the most influential person in shaping the post-World War II sound of the Chicago blues.
