What can be said about Willie Dixon that hasn't been said already?
Willie was not only a great singer and bass player he was a master songwriter and a very important bluesman.
Willie has been copied by many and influenced blues muscians as well as rock and roll musician's.
Some less obvious than other, think Steve Marriot Humble Pie and the Black Crowes who without Dixon's influence may have just been bands that copied Willie or took directly from Willie's style and made it their own.
