The late Aldo Clementi, master of the mystery and magic of highly systematic music, is celebrated close to the first anniversary of his death. L'orologio di Arcevia, a spellbinding piece of elaborate clockwork for tuned percussion instruments, is paired with his Madrigale, for piano and tape. Lachenmann’s astonishing percussion solo Intérieur I and Kurt Schwitters’ celebrated but rarely performed Ur Sonata, or grandfather of all sonatas, complete the program. Ace percussionist Steven Schick is the featured performer, turning himself inside out for the untamed vocalizations of the Schwitters classic.
