For a fourth year, this Paris-born celebration fills New York's streets and public spaces with free, festive sounds. Classical cognoscenti will get into a groove with the various Xenakis concerts, including the Yale Percussion Group at Central Park's Naumburg Bandshell (12noon), a plethora of percussionists performing Persephassa from the Central Park Lake (4:15 and 5:45pm) and Luca Vegetti directing a marionette version of the composer's only opera, Oresteia (1–10pm).Other local performers include Face the Music, the Dessoff Choirs, Composers Collaborative and American Opera Projects.
