There's going to be a conference on Nadia Boulanger in Boulder. She taught a good number of the American composers on the list.
Pierre Boulez (Repons) talks.
The invaluable Robert Gable links to a not-so-valuable "bio" of John Cage (Sonatas and Interludes, 4'33"). This is really just an excuse to highlight this great blog.
