He was the gentle rebel of soul: Marvin Gaye, one of the greatest musicians of the 20th century. With his unmistakable voice and hits, he left an indelible mark on American pop culture—one that endures to this day.

With his signature gospel sound on the Hammond B3, Billy Preston doublehandedly elevated the greatest artists of his time – from the Beatles to the Rolling Stones, from Aretha Franklin to Eric Clapton, from Ray Charles to Barbra Streisand to Sly and the Family Stone. In our film, we explore Billy's career and influence on generations of musicians, as he scored several number one hits of his own and became one of the most sought-after musicians in the world. He did all of this as a soul divided -- by his deep roots in the church, in constant conflict with his identity as a gay Black man, searching for a family of his own that would accept him for who he was.
