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 RB charts for eight weeks after being sold to Chess. From then on, Mabon was a Chess artist, returning to the top RB 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 RB 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. ~ Bill Dahl, Rovi
