One of the first “contemporary Christian groups” I listened to when I was young was The Imperials. When I started listening their lead singer was Russ Taff. Not long after that, Taff went solo and had some great songs and albums.
I never knew what happened after that, but this documentary on his life fills in the rest of the story. It’s on Amazon Prime now, if you subscribe. It is a heart wrenching story of early abuse that then grows into his own personal addictions. In all of it is the grace of God, the strength of a family, and the beauty of the Body of Christ.
