Bill Hare is an American Grammy Award-winning audio engineer known for pioneering contemporary recording techniques in a cappella. He was the first to record voices individually, and the first to mic singers exactly as one would mic instruments. Over the course of his career, Hare has become well known for his outsize role in shaping the sound of recorded a cappella. Industry observers have called him the "patriarch" and "the Dr. Dre" of a cappella recording. Deke Sharon, founder and longtime president of the Contemporary A Cappella Society, wrote of Hare's influence in 2018: "The sound of contemporary recorded a cappella owes more to his technique, style, and pioneering than any other person."
