Kronos Quartet teams with Terry Riley on a Nonesuch release that recasts Riley’s Post-Modern material through a Neo-Classical string lens — Requiem for Adam and Philosopher’s Hand unfold as slow-moving arco studies and pulsing ostinatos. Taut bowing, sustained harmonics and Riley’s modal repetitions spotlight timbre and temporal suspension, situating the performances squarely between Neo-Classical clarity and Post-Modern process.
