Hosted by Jad Abumrad of New York Pulic Radio, the Wordless Music Series takes innovative artists from around the world and asks them to perform with more traditional chamber and new music performers, forcing them to improvise on how they present their music.

In this episode: Violin/Piano duo Colin Jacobsen and Katya Mihailova perform Arvo Pärt's "Fratres"; vocalist Abby Fischer premieres Nico Muhly's "Mothertongue," and Toronto-based songwriter/producer Sandro Perri (a.k.a. "Polmo Polpo") performs his own set.
