Five years ago, 18-year-old violin student William Harvey spent an extraordinary night performing for firefighters and National Guardsmen who were working to clear the site of the World Trade Center towers. We met Harvey in 2001, and Fred Child has a follow-up conversation with him to mark the fifth anniversary of Sept. 11. That evening changed the course of Harvey's musical life. We'll also hear him in concert, playing the Adagio from the Violin Sonata in D Minor by Camille Saint-Saens. He's joined by pianist Jeannette Koekkoek, in concert at Indiana University in Bloomington.
