2010 marks a milestone for America's premiere independent label, Rounder Records: 40 years in the music industry. To celebrate, Rounder held an anniversary concert on October 12th at Nashville's Grand Ole Opry. Grammy-winning Rounder artists Alison Krauss & Union Station featuring Jerry Douglas, Mary Chapin Carpenter, Béla Fleck and Irma Thomas performed at this momentous celebration along with musical host, Minnie Driver, and special guests Nathan & the Zydeco Cha Chas and Jazz/R&B pianist, Henry Butler. Steve Martin's show at the Ryman Auditorium the night before was also filmed and select performances from that show are included on the album. In addition, performances from Alison Krauss and Robert Plant's 2008 CMT Crossroads are included, as well as performances from Madeleine Peyroux's 2009 concert in Los Angeles.
