Bang on a Can All-Stars Present David Lang’s before and after nature with the Los Angeles Master Chorale.

Pulitzer Prize and Grammy-winning composer David Lang’s newest work-before and after nature-is a monumental meditation on how people might imagine the world both before and after human existence. Featuring two boldly innovative ensembles familiar to Krannert Center audiences-Bang on a Can All-Stars and the Los Angeles Master Chorale-and paired with stunning video/visual design by Tal Rosner, before and after nature explores how people interact with the natural world, concentrating particularly on the things we don’t really see or understand.
