Blues harmonica master Sonny Boy Williamson II defined the urban blues-harp style with his 1950s recordings, and NINE BELOW ZERO collects a generous batch of his best. Signature tunes such as "Don't Start Me Talking," the title cut (from which a U.K. pub-rock band once took their name), and "Eyesight to the Blind" are classic examples of Williamson's trademark sound--thick, lazy vocals, and visceral harmonica work so expressive it could almost be a human voice. Not all of Sonny Boy's biggest songs are included here, but NINE BELOW ZERO still makes for one heck of an introduction.
