Montgomery Gentry has been added to a 2014 Headwaters Country Jam lineup that keeps getting bigger and better. The country duo will join previously announced stars like Dustin Lynch and Sammy Kershaw for the three-day festival near Three Forks, Mont.

LoCash Cowboys and Chase Rice are also locked in for the June 26-28 camping and country music festival at the Bridge, with more lineup announcements coming soon! Ticket and camping packages are on sale now at the official Headwaters Country Jam website, including VIP packages that include free beer. Yes, free beer!

The Bridge is a 158-acre campground that's been the home of Headwaters since it started in 2008. Eric Church, Eli Young Band and Luke Bryan are just a few of the stars that have played this festival in recent years. Aside from the music, festival-goers will find horseshoe tournaments, dance contests, mechanical bull riding and plenty of food and merchandise keep you busy between acts.
