Chester Burnett's ferocious growl was a staple of Chicago's electric-blues heyday. This 20-song compilation ranges from his 1951 debut "Moanin' at Midnight" with Willie Johnson on guitar to 1964's "Killing Floor" with Buddy Guy on guitar. His scratchy, sawed-off vocal approach and his energetic harmonica grace original classics such as "How Many More Years" and "Smokestack Lightnin'". By 1960, he became, along with Muddy Waters, the foremost interpreter of Willie Dixon's songs, lending his coarse voice to legendary Dixon cuts such as "Wang Dang Doodle", "Back Door Man", "Spoonful", "The Red Rooster", and "I Ain't Superstitious". Wolf's style was based on primal raw power, and he ranks among the genre's most distinctive performers. --Marc Greilsamer
