Milton Babbitt has died at 94. Times obit here; WQXR notice here (via Soho the Dog); Sequenza 21 notice here.
Update: do check out the Babbitt documentary by Robert Hilferty, completed by my Tanglewood classmate Laura Karpman and found here.
Updates #2-5: David Rakowski offers a lovely memorial essay at New Music Box. A good interview with Milton here. And a reminiscence by soprano Judith Bettina here. And yet another interview here.
Update #6: Jim Ricci has recently posted his own reminiscences.
