This is your chance to catch innovative young maestro Justin Brown, who has been invigorating the Deep South's classical music scene with impeccable interpretations of the standards; he has also spearheaded a significant commissioning program. Tonight's concert reflects these dual interests, with the New York premieres of Avner Dorman's Astrolatry and Paul Lansky's Shapeshifters for Two Pianos and Orchestra (featuring piano duo Quattro Mani) played alongside Beethoven's Seventh Symphony.
