St. Botolph's Town brings news that Opera Unlimited will be presenting the American premiere of Peter Eötvös's opera Angels in America in June. For more about this new-ish Boston-based organization, which is a joint venture by the Boston Modern Orchestra Project and Opera Boston, see David Weininger's article in the Boston Phoenix. Tom Meglioranza, who gave a superb recital of modern American songs at Symphony Space last week, will star as Prior Walter. Farther north, CBC television is presenting several new operas on its Opening Night series. One of them is Alexina Louie's Burnt Toast, a cycle of comic operas done in TV-drama style. I don't know Louie's music, but she has a distinguished resumé. There are various amusing extras at the Burnt Toast site, including a feature called Operagrams, which, starting Feb. 27, will apparently enable you to send personalized phone messages via a professional opera singer. Preview messages are cast in such familiar aria forms as "Drunken Dial" and "Booty Call."
