"Both the symphony and the quintet display a gift for drama and for lyricism, expressed in sophisticated colors and textures. There’s verve in the rhythms and invention in the harmonies; the tunes catch the ear. Movement by movement and start to finish, the architecture has a sturdy logic that does not preclude surprise. It’s an impressive debut. And Mr. Greenberg is just 14." -- Matthew Gurewitsch, The New York Times
