In 2009–10 I will be writing an extended work for string quartet and voice, for the Brooklyn Rider String Quartet and myself as vocalist. This project represents a continuation and deepening of my collaboration with these four remarkable musicians, who have performed and recorded my music in various guises as soloists (most recently, the violinist Colin Jacobsen recently premiered my Double Violin Concerto) and in their roles as leaders of the Knights Chamber Orchestra. The piece will have two sections, one with voice and one without, so that they can bring me along for their 2010–11 season tour; the group can also perform the work when I am not with them on the road. The work will be commissioned jointly by the Brooklyn Rider and Market Square Concerts in Harrisburg, Pennsylvania, where the vocal section will be premiered in February 2010.
