Musicians can go to eventful.com/littlebigtown to participate. The competition, which begins Jan. 21, will continue through 2 p.m. PT, Feb. 27, on Eventful. The winning bands will be announced Feb. 27. Fans across the nation can vote for their favorite acts by using Eventful’s Demand service. The four acts with the most Demands will perform at different stops on the tour during March. "In the past Little Big Town has had amazing opportunities as an opening act,” says Little Big Town’s Karen Fairchild. “We’ve had the honor of opening for John Mellencamp, George Strait, Martina McBride, Sugarland, Keith Urban and more. Because of our experiences, we wanted to find a way to give back to some bands that are just getting started in their careers. It's even more special because the fans get to choose. I can’t wait to see who the fans select.”
