This week: A spotlight on Grammy-nominated Kayhan Kalhor. He's a virtuoso of the traditional Persian instrument, known as the Kamanche, a type of Persian fiddle. Kayhan talks to us about his upcoming CD called "Silent City," a collaboration with an American string quartet known as the Brooklyn Riders (set to be released in Spring 2008) and about what it was like to work on the soundtrack of the latest Francis Ford Coppola film called "Youth Without Youth."
