Ecstatic Summer: David Lang with A Far Cry and Oneohtrix Point Never

River to River Festival. Bang on a Can cofounder David Lang's languid work for strings, Darker, will be reimagined by Daniel Lopatin, a.k.a. electronic-music star Oneohtrix Point Never. Lopatin will also present his own work, specially arranged for A Far Cry, a hot young conductorless orchestra from Boston.
