A few years ago, Jay Shefsky introduced us to banjo prodigy Noam Pikelny. Pikelny had just joined mandolin virtuoso Chris Thile as part of his band, Punch Brothers. Now Pikelny, a Skokie native, is nominated for a Grammy for his solo release, "Beat the Devil and Carry a Rail." Jay caught up with Punch Brothers before a performance at Ravinia. We take another look on Chicago Tonight at 7:00 pm. The 55th Grammy Awards take place on Feb. 10, 2013.
