On the next Modern Notebook with Tyler Kline: Called a “dream group” by The New York Times after just one concert, the ensemble Owls brings together members of Kronos Quartet and acclaimed soloists. Their debut album Rare Birds is built on joy, curiosity, and experimentation — ending with a 14-minute celebration of minimalism and 5/4 rhythm by Terry Riley.

Then: A single chord for viola grew into something unexpected for composer Karin Rehnqvist — a piano improvisation, then an electronic voice that sounded like the sea. In her piece “I thought the sea would sing to me,” she explores the viola’s depths, from the warmth of the C string to shimmering quarter tones and playful musical gestures.
