The Queen of Soul has left us, but “Amazing Grace,” a documentary shot at New Bethel Baptist Church in Los Angeles in January 1972, lets fans enjoy Aretha Franklin at the height of her earth-shattering power. According to Rolling Stone, the film—which was directed by Sydney Pollack (“Tootsie”)—was unreleased due to technical and legal issues (Franklin filed an injunction in 2015 to prevent it from screening at the Telluride Film Festival). But it will finally get a wide theatrical release on April 5. The magazine says the film’s live soundtrack is one of Aretha’s greatest albums of all time. The newly-released trailer is already garnering raves; check it out.
