Thanks to Chris Thile for joining us to talk about tonight’s Punch Brothers show at the Palace Theatre and the group’s new album Hell on Church Street.

The Punch Brothers’ style has been described as "bluegrass instrumentation and spontaneity in the structures of modern classical”. Just what is bluegrass? It’s a style of music that is traditionally played on acoustic stringed instruments and emphasizes the off-beat, often improvised and with high energy.

For today’s 9:30 Coffee Break, what bluegrass and bluegrass-influenced songs do you want to hear?
