Did you feel that? The earth just moved, since the fine folks at Aftershock, aka Northern California's biggest summer rock festival, have announced the impressive and expanded lineup for this year's event, with Five Finger Death Punch confirmed as the Sunday night co-headliner. 

The second annual Aftershock Festival will be held Sept. 14 and 15 at Discovery Park near downtown Sacramento, Calif. New additions to the roster of performers include the aforementioned 5FDP, along with Testament, Filter, Miss May I, Thousand Foot Krutch, Love and Death, We as Human, Eye Empire, Gemini Syndrome, Girl on Fire and Butcher Babies. That's a whole lot of rock, and yes, expect the earth to move.

"We're excited to take the new albums out on the road so fans can hear some of the new music live,” says Five Finger Death Punch vocalist Ivan Moody. “And what better way to kick off our fall tour than with a massive festival like Aftershock?"

The updated daily band performance lineup for Monster Energy’s Aftershock Festival is as follows, as the bands will perform across the event's three stages. What, you thought only two stages could handle all this rock? The foundation of the dwellings would crack!
