Billy Preston was 5 years old when he sang backing vocals for gospel legend Mahalia Jackson and, across the course of his six-decade career, he went on to contribute his signature sound to some of the greatest artists of his time—including The Beatles, The Rolling Stones, Barbra Streisand, Sly Stone, Ray Charles, Rufus, and Eric Clapton. At the same time, Preston established himself as a GRAMMY-winning solo artist, but, despite his success, he struggled to reconcile his deep relationship with the Black church with his sexuality, setting off a lifelong quest to find love and acceptance.
