The Crossing: David Lang's Lifespan

The Crossing: David Lang's "Lifespan," a new installation at the Cleveland Museum of Art, features three vocalists whistling and breathing around an Allora and Calzadilla sculpture, to subtly move a Hadean-period rock like a pendulum. The Philly-based choral group will perform a piece by American composer David Lang, commissioned by the Philadelphia Museum of Art. Performance take place throughout the day today, tomorrow and Sunday in Gallery 218. Admission is free. (Niesel)
