"Schtyx are charts, bones, professions, shades, numbers, glues, hypes, acts, devils, organgrindings, wood implements, jugglers, chance operations, performance art, the Yiddish underground," writes composer Alvin Curran. His wonderfully irreverent and lyrical music blends an array of compositional practices into a singular musical language. Two recent chamber works by Curran's longtime friend Frederic Rzewski—a 4-minute canon dedicated to Elliott Carter, and the witty and improvisatory Pocket Symphony—share the program with Feldman's hypnotic Viola in My Life II.
