The three movements of these broken wings concentrate on three different physical and musical challenges. The first movement consists of music that requires incredible stamina and intense concentration. Sad, falling gestures dominate the slow second movement, and I gave the vague but hopefully inspiring instruction that the players should drop things when they are not playing. In the last movement I wanted to make a music that danced and pushed forward, in the hope that it would encourage the musicians to do so as well. —David Lang
