The conversation gets ever livelier at Sequenza 21, where composers of all stripes thrash through old internecine debates — atonality good or bad, 12-tone music dominant or nonexistent, John Adams overrated or very overrated, etc. — and sometimes deliver deliciously brittle reviews of colleagues. The composer-as-critic is a tradeoff I'll always happily take: professional biases and jealousies may come into play, but the opinion is never fuzzy around the edges. The layout of the site is complex, like a Knotty Twelve-Tonish Figure. There's the forum on the main page, also a Composers Forum and individual composer blogs.... Bryant Manning is keeping it spunky on Mysteries Abysmal, as his blog has been renamed.... Take note again of Heather, very thoughtful pianist in Oakland, and of The Laurel Letters, offering beautifully composed reviews of Boston musical life.... Vilaine fille reigns supreme.
