The opening track of Sonic Youth’s nervy score for Simon Werner a disparu, “Theme for Jérémie” starts with a sparse clatter of percussion and guitars that creak like rusty hinges, establishing an atmosphere of dread that’s perfect for a thriller about mysterious events at a French high school. While the ghostly “Les Anges du piano” is equally effective at keeping viewers on edge, the turbulent likes of “Dans les bois/M. Rabier” expose the aggression that roils underneath even Sonic Youth’s most seemingly placid music.
