Featuring “some of the brightest young classical musicians in the world” (Time Out New York), Decoda is Carnegie Hall’s first-ever affiliate ensemble, comprising alums of the adventurous Ensemble Connect. This season, as part of Carnegie Hall’s United in Sound: America at 250 festival, the spectacularly versatile group presents American Renaissance—a program of works by Charles Ives, William Grant Still, Carlos Simon, Margaret Bonds, Sarah Elizabeth Charles, Zenobia Powell Perry, and Florence Price.
