Once one of the most visible and winning jazz vibraphonists of the 1960s, then an R&B bandleader in the 1970s and '80s, Roy Ayers' reputation s now that of one of the prophets of acid jazz, a man decades ahead of his time. A tune like 1972's "Move to Groove" by the Roy Ayers Ubiquity has a crackling backbeat that serves as the prototype for the shuffling hip-hop groove that became, shall we say, ubiquitous on acid jazz records; and his relaxed 1976 song "Everybody Loves the Sunshine" has been frequently sampled. Yet Ayers' own playing has always been rooted in hard bop: crisp, lyrical, rhythmically resilient. His own reaction to being canonized by the hip-hop crowd as the "Icon Man" is tempered with the detachment of a survivor in a rough business. "I'm having fun laughing with it," he has said. "I don't mind what they call me, that's what people do in this industry."
