Beginning this weekend, Bowerbird in Philadelphia is presenting American Sublime, a seven-day festival of late works of Morton Feldman. Marilyn Nonken will play Triadic Memories; JACK will perform Structures alongside Cage's String Quartet in Four Parts; Joan La Barbara will sing Three Voices; and, at the end, FLUX will reprise Quartet II. It's the most extensive tribute I can remember seeing on these shores, bigger than Lincoln Center Festival's Feldman series of 1996. The organizers generously credit me with the title, although the phrase in fact comes from an infinitely higher authority.... Roulette will inaugurate its new Brooklyn space with a pair of Cage Musicircuses this weekend.... Jody Oberfelder Dance Projects will present a new version of Stravinsky's Histoire du soldat on June 9, 10, and 11, shifting the story into a modern landscape of reality TV and political hype. The British actor Christian Coulson is the Narrator; the Knickerbocker Chamber Orchestra performs.... On June 9, at Merkin, David Krakauer and Ensemble 212 give the world premiere of Tahrir by Mohammed Fairouz.... Anne Midgette has a lovely review of Meredith Monk's Songs of Ascension, which is one of my current Recommended CDs.... More than fifty works of Xenakis will be performed at the Flâneries musicales de Reims in July.... The complete Make Music NY schedule has been posted.
