I uploaded this on Jan 29th in honor of Willie Dixon, on the anniversary of his death back in 1992. From the 1940's until his death, his contributions to blues, and rock & roll are inumerable, and include a catalog of over 500 songs. Notable as songwriter, backing musician, bandleader, arranger, producer, businessman and touring ambassador. Here's a clip of the man in 1981, playing with Arthur Dixon on piano, Johnny Watkins on guitar, Freddy Dixon on bass, Jimmy Tillman on drums, and Sugar Blue on Harmonica.
