The goal of the America! series from harmonia mundi is to explore the profound effect that the ''New World'' has had on the world of classical music. Featuring some of the finest performers on the label, each of the three volumes focuses on a theme. Volume 2 looks at the huge impact made by George Gershwin. Subtitled From Broadway to the Concert Hall, this collection features the unique mix of classical and jazz sensibilities that was the hallmark of Gershwin's style.
