March 7, 2011 marked a brave direction for Lincoln Center’s Tully Scope Festival with an evening of music exclusively by composers who are (gasp!) still alive. This concert, which featured the music of Tyondai Braxton along with works from John Adams, Caleb Burhans, and Louis Andriessen was an important inclusion in this exciting and eclectic festival. Tully Scope would reinforce the importance of programming living composers two nights later with Kayhan Kalhor and Brooklyn Rider’s even more daring presentation of works by living composers including the New York premiere of Jacobsen’s “Beloved, do not let me be discouraged” and the World Premiere of Philip Glass’ “Suite for String Quartet from Bent.”
