This orchestra of gifted youngsters itching to prove themselves takes to Carnegie Hall's main stage under the direction of David Robertson in a vibrant program of classics, including Bernstein's "Symphonic Dances From West Side Story" and Mussorgsky's "Pictures at an Exhibition." Gil Shaham adds star power for Britten's Violin Concerto (Op. 15). There's also a premiere, Samuel Adams's "Radial Play," commissioned by Carnegie Hall.
