Besides drummer jokes, there might be almost as many viola jokes tied for the lead in musical humor.  We'll put all that aside for this New Sounds program, where the viola takes center stage, not necessarily as a solo instrument in a concerto or a chamber setting.  Hear new works for viola, some for viola & electronics, and viola d'amore.  From a forthcoming record by new music champion Nadia Sirota, listen to a piece by Missy Mazzoli, "Tooth And Nail."
