"The National Symphony Orchestra's unprecedented digital recording cycle offers an opportunity to experience my father's compositional evolution in context for the first time. Peter Laki's text, Frank Schramm's photography, and, of course, the committed artistry of Maestro Noseda and the musicians make a compelling argument for this music's enduring significance." – Gregory Walker, son of George Walker
