A punk rock duo drummer and former addict must reckon with loss of hearing and learns profound lessons about life’s crafty way of altering the rhythm in Darius Marder’s powerful drama The Sound of Metal (B+). The film is a marvelous showcase for the prodigious talent of Riz Ahmed in the lead role, and he is riveting in his painful and touching journey. The ensemble is roundly terrific, from Olivia Cooke as the other half of the protagonist’s band as well as his gypsy love interest, plus Lauren Ridloff and Paul Raci as supportive hard knocks teachers in the deaf community and Mathieu Amalric who makes a superb final act impression. Marder handles the story sensitively without ever devolving into movie of the week level melodrama. The film’s stunning sound design and lived-in performances provide the story with fresh resonance, and not every plot point goes exactly as planned. Expect to be moved by the percussive force of this earnest and engrossing human story and to witness Ahmed at the top of his craft.
