A maverick Jewish record producer with an ear for black music teams up with artists considered behind the times to produce albums — actual vinyl — that reinvigorate mainstream pop. This isn’t Cadillac Records, the new film biopic of Leonard Chess and Muddy Waters, but the true and right-now story of Gabriel Roth, Daptone Records, and a roster of soul and gospel artists with much deeper roots in the blues than the most famous singer to record at Roth’s Bushwick, Brooklyn studios, Amy Winehouse. Saki Knafo delivers a terrific portrait of Roth and his recording artists for The New York Times Magazine, and he’s smart enough to understand that this is a story about religion as well as race. Roth compares great gospel and soul music to Yiddish literature; the gospel musicians for whom he writes songs think that’s just fine.
