They join previously announced headliners Brad Paisley and Toby Keith.
The Tree Town Music Festival will also include a "Little Nashville," a stage that will resemble Nashville's Broadway. It will open to all campers and ticket holders on Friday, May 23 from 6 p.m. to 2 a.m. and be available throughout the entire festival weekend. Beer tents and food vendors are just a few of the things that will be open.
Tickets run $120 (early-bird special) for two-day general admission passes until March 14th. The campground has over 1800 campsites amidst the hills of Heritage Park and those run for $100.
