White Horse Pictures' new documentary showcases the life and impact of Billy Preston. Nobody in the history of 20th-century music has been such an integral part of so many divergent scenes, from Gospel to the Civil Rights Movement, to Swingin’ London and the British Invasion, to the 1970s onslaught of Rock ‘n’ Roll, Funk, and Soul to the Folk tapestry of Topanga Canyon. Though Billy’s life was riddled with struggle and trauma, his story ends with a comeback: Billy’s towering musical accomplishments are matched only by his triumphant personal journey of self-love. Despite his preternatural talent which earned him a place on stage beside the biggest names in 20th-century musical history, what makes his tale so compelling is Billy’s personal journey towards self-acceptance. His story is a stark reminder of how far we’ve come as a society, and how far we still have to go.
