Mostly Mozart Festival: International Contemporary Ensemble

It may be Mostly Mozart, but this year's August festival also features lotsa Stravinksy, with a nine-part series dedicated to the 20th-century musical icon. Tonight, the local new-music cabal begins a three-year residency with Mostly Mozart with a thorough overview of Stravinsky's polymorphous styles. Like Haydn's Farewell Symphony in reverse, the concert opens with a playerless piano (Study for Pianola) and then slowly adds players for duos, trios and quartets, culminating in the intense Concerto for Piano and Winds, with Peter Serkin as soloist and Pablo Heras-Casado on the podium. The Stravinsky worship continues at an after-party at the Kaplan penthouse, where ICE plays his Pour Pablo Picasso, Epitaphium, Octet and arrangements of Bach, plus Igor homages by Finnissy, Denisov, Carter, Schnittke and Berio.
