Music at the Northfield Public Library, 4:00 p.m., 115 Main St., Northfield, MA

We’ll focus on music of Appalachia, including some traditional a cappella treasures. Jim Armenti joins us on exquisite mandolin and Joe Blumenthal drives the bus with his upright bass. But we’re also excited to share a young lesbian love song. The concert takes place upstairs in the spacious Children’s Room, available by stairs and elevator.
