Pianist Jon Nakamatsu joins us to talk about the common theme running through this weekend's Toledo Symphony concerts: the infamous Dies Irae (Judgment Day) chant melody, which has appeared in hundreds of works (Jon plays Liszt's Totentanz and Rachmaninov's Rhapsody on a Theme of Paganini). Also on the concert, the psychedelic Fantastic Symphony (Symphonie Fantastique) of Hector Berlioz.
