Double bassist Edgar Meyer and Nickel Creek's mandolin player Chris Thile have joined forces on a new album that explores the intersections between classical and American roots music. The album features 12 original compositions by the duo, which has been performing together sporadically for the past several years. They join us today with a live performance.

Edgar Meyer and Chris Thile perform tomorrow at 8 p.m. at the Stern Auditorium in Carnegie Hall.
