La signora Dawn Upshaw -- mystical Unitarian, corageous survivor, proud disciple of the Upshaw Family Singers, radio DJ, polite endurer of dense journalists, friend of the late Lorraine Hunt Lieberson, and soprano assoluto of magical wonders -- with dancer Michael Schumacher will perform the New York premiere of La Passion de Simone at the 2008 Mostly Mozart Festival next Wednesday. Kaija Saariaho’s "musical journey in fifteen stations" (as in "stations of the cross") is directed by Peter Sellars, with text by Amin Maalouf.
NPR has plenty of audio, and other good stuff.
