Willie Dixon "I Am the Blues" CD. The Vicksburg, Mississippi, native and Chess Records righthand man — Willie Dixon — wrote songs for Muddy Waters, Howlin' Wolf, Koko Taylor and many other blues legends. He also played upright bass on countless classics. And on top of all that, he could sing as he does here, wonderfully. On this 1970 LP, he performs I'm Your Hoochie Coochie Man, The Little Red Rooster, Spoonful, Back Door Man and more.
