"These are my friends. I love their music. They are among the most important people in my life. The portrait is shattered because I could not make it whole." If you're bored this weekend, check out Robert Ashley's Music with Roots in the Aether. Each episode features a "landscape" (unusually-staged informal discussion) with a contemporary American composer, followed by a one-hour performance of his or her work. Subjects include the recently discussed Alvin Lucier, Pauline Oliveros, and Philip Glass. More on Ashley from NewMusicBox and Ubu.
