Premiered November 13, 2007 by The Krosnick and Kalish Duo, Paul Hall, Juilliard School of Music. Mr. Krosnick and Mr. Kalish were joined by Darrett Adkins, a cellist, and Christina Dahl, a pianist, for Richard Wernick's spirited, grandly scaled Double Duo (2004), a piece that works its magic by having the pairs of pianists and cellists begin in tandem and gradually find their independence. subtle changes of texture were everything. (Allan Kozinn, New York Times Music Review) (Dur.: 13' 30)
