Rumors about the third annual Rockstar Energy Uproar Festival (Mayhem Fest’s sister tour)started to spread last March. This morning, though, the lineup has been officially announced for the late Summer/Fall tour, and with a few exceptions and added bands, the rumors are true.

Shinedown, Godsmack, Staind, and Papa Roach will indeed perform on the main stage along with Adelita’s Way. P.O.D. will be headlining the Ernie Ball and Jägermeister Stages, also featuring Deuce (Hollywood Undead singer), Fozzy, Redlight King, Mindset Evolution, In This Moment, Thousand Foot Krutch, Candlelight Red and a local battle of the bands winner. “Nothing makes us feel more at home than playing the best festival in the U.S. with the baddest-ass line-up of the year! You better hold on to your hats America, ’cause this fall we’re coming at you hard ‘n loud with the power hour Smackdown,” Godsmack drummer Shannon Larkin said about the tour.

While the touring festival will take place in August and September, exact cities and venues have yet to be revealed. Uproar Fest did, however, upload a video featuring bands on the bill revealing the tour. You can watch this introduction video after the jump.
