Willie Dixon was the ultimate blues songwriter, sideman, producer, and a monster force in post-war Chicago Blues as well as a decisive influence on modern rock & roll. Perhaps one of the first blues songwriters to benefit in a substantial, gainful way from his work, he helped Muddy Waters, Howlin Wolf, and others find their most profitably triumphant voices, writing dozens of classic blues songs; many of these were covered by superstar British rock acts in the 60s and 70s, including the Rolling Stones, Cream, and Led Zeppelin.
