from 03 - This New, Immense, Unbounded World. From Robert Kapilow's '03: This New, Immense, Unbounded World, a musical tribute to the Louisiana Purchase of 1803, this movement establishes the experience of both the explorers and the native people who lived in the territory. According to Kapilow, Lives were both ended and expanded; it (the era) was simultaneously wonderful and terrible. Musically, it is an imaginative marriage of poetry and melody into a remarkable musical creation. Recorded by the Young People's Chorus of New York City; Francisco J. Nuñez, Artistic Director.
