Based on a true story, Virtuoso, part biography, part ensemble piece, tracks the lives of two people and those with whom they interact during and after the second World War. The work shows how music played a critical role in their survival and in rebuilding their lives. Set in locations around the world, with a focus on Germany and the United States, the book portrays the global impact of the war and the power of music to traverse geographic and political boundaries and bring people of all cultural backgrounds together.
