Performance time - ca. 4:45 One of America's most historic moments was accompanied by this very unique work, composed especially for the occasion and performed by a quartet of America's finest artists - Yo-Yo Ma, Itzhak Perlman, Anthony McGill, and Gabriela Montero. Maestro Williams has rescored his monumental work into a dramatic movement for string orchestra - a stunning display of emotion, musical power and grace. An advanced level piece for mature groups.
