The recommendations don't particularly capture the "new" of "new" american classical music but click on the American classical music link for a rather good starter set of "legacy" CDs. The Barber, Ives, Partch, Glass, and Reich have been essential to my American classical music education and the Griffes is a recent favorite. Still don't like Howard Hanson, though.
