Importantly, the festival isn't limited to the groups that have a heavy radio presence: It makes an effort to show country's breadth and depth. A number of prominent figures from previous generations are playing, like Steve Earle and Merle Haggard. Sturgill Simpson, a relative newcomer with a '70s-indebted sound, will perform, as will Lydia Loveless, whose music veers closer to classic rock. Speaking of classic rock: ZZ Top and Greg Allman are making appearances as well. On the other end of the age spectrum, fans can find youngsters like Maddie & Tae and the Brothers Osborne.
