The sly, insinuating vocals and chunky piano style of Willie Mabon won the heart of many an R&B fan during the early '50s. His salty Chess waxings "I Don't Know," "I'm Mad," and "Poison Ivy" established the pianist as a genuine Chicago blues force, but he faded as an R&B hitmaker at the dawn of rock & roll. Mabon was already well-grounded in blues tradition from his Memphis upbringing when he hit Chicago in 1942. Schooled in jazz as well as blues, Mabon found the latter his ticket to stardom. His first sides were a 1949 78 for Apollo as Big Willie and some 1950 outings for Aristocrat and Chess with guitarist Earl Dranes as the Blues Rockers.
But Mabon's asking price for a night's work rose dramatically when his 1952 debut release on powerful Windy City DJ Al Benson's Parrot logo, "I Don't Know," topped the R&B charts for eight weeks after being sold to Chess. From then on, Mabon was a Chess artist, returning to the top R&B slot the next year with the ominous "I'm Mad" and cracking the Top Ten anew with the Mel London-penned "Poison Ivy" in 1954. Throughout his Chess tenure, piano and sax were consistently to the fore rather than guitar and harp, emphasizing Mabon's cool R&B approach. His original version of Willie Dixon's hoodoo-driven "The Seventh Son" bombed in 1955, as did the remainder of his fine Chess catalog. Mabon never regained his momentum after leaving Chess. He stopped at Federal in 1957, Mad in 1960, Formal in 1962 (where he stirred up some local sales with his leering "Got to Have Some"), and USA in 1963-1964. Mabon sat out much of the late '60s but came back strong after moving to Paris in 1972, recording and touring Europe prolifically until his death.
