Judd Greenstein is a Brooklyn-based composer of structurally complex, viscerally engaging works for varied instrumentation. A passionate advocate for the "indie classical" community in New York and beyond, much of Judd's work is written for the virtuosic performers who make up that community, and is tailored to their specific talents and abilities. His work has been heard at venues such as the Tanglewood Festival of Contemporary Music, Amsterdam's Musiekgebouw, the Bang on a Can Marathon, and the MusicNOW festival; major recent commissions include those from Carnegie Hall, Present Music, ETHEL, the Seattle Chamber Players, yMusic, and Roomful of Teeth, as well as a 30-minute work for the Minnesota Orchestra's Inside the Classics series. His work, "Change", for NOW Ensemble, was recently chosen as one of NPR Music's "100 Favorite Songs of 2011".

In addition to his work as a composer, Judd is active as a promoter of new music in New York and around the country. He is the co-director of New Amsterdam Records/New Amsterdam Presents, an artists' service organization that supports composers and performers whose work is open to all influence, regardless of genre. He is the curator of the Ecstatic Music Festival in New York's Merkin Hall, an annual showcase of new collaborative concerts between artists from different musical worlds, and he is a founding member of NOW Ensemble, a performer/composer collective that develops new chamber music for their idiosyncratic instrumentation of flute, clarinet, electric guitar, double bass, and piano. Judd has studied at the Tanglewood Music Center and the Bang on a Can Summer Institute and holds degrees from Williams College, the Yale School of Music, and Princeton University.
