NEW YORK This year's festival is aiming to organize more venues, with events planned in Flushing, Jamaica, Jackson Heights, Astoria and Long Island City. Musicians wishing to participate may sign up at www.timeoutnewyork.com/makemusic. Arrangements should be complete by May 1, , but performances by musicians not signed up by that date may still happen, as an aspect of the event is meant as the spontaneous happening of music around the city.
