You can now add several more top talents and one more venue to that list: Loretta Lynn, Steve Earle and Gillian Welch top the bill for a one-time-only concert at the brand-spankin'-new Ascend Amphitheater.

Tift Merritt, Eric Heywood, Nikki Lane, Emmy Rose Russell and more performers TBA will also be a part of the two-stage "mini-festival" within a festival on Sat., Sept. 19. Tickets will range from $25-$75 and go on sale Friday, July 31 at 10 a.m. No direct link is available yet, but one should soon appear on the Ticketmaster site here.
