Robert Mugge's GOSPEL ACCORDING TO AL GREEN examines the turbulent career of soul singer and gospel preacher Al Green. - GOSPEL ACCORDING TO AL GREEN looks at Green's transition from hugely successful soul singer to gospel artist and fundamentalist preacher. Filmed in concert in Washington, D.C., in rehearsal in his recording studio, in a service at his Memphis church, and in an extended interview, Green reveals himself to be an electrifying performer, whether singing love songs to women or spiritual ones to God.
