Contemporary music producer Elizabeth Huston presents KLANG: Die 24 Stunden des Tages (Sound: The 24 Hours of the Day), a daylong series of chamber music compositions by pioneering composer Karlheinz Stockhausen each written to represent an hour of the day. Intended to include 24 pieces but left incomplete at the time of Stockhausen’s death in 2007, this 21-part work has never been performed consecutively as originally intended. Performed by an ensemble of Philadelphia-based musicians, the 14-hour marathon performances include music that ranges from intimate chamber pieces to innovative electronic compositions. The production features performances by Cologne’s MusikFabrik, light paintings by Thomas Dunn, and sound projection by Dolph Kamper.
