Sat., Sept. 14, through Sun., Sept. 15; Aftershock 2013
Discovery Park, 11 a.m., $59-$219
Just go ahead and plan to be sick on Monday, because after the Aftershock 2013 festival, you won't be fit to work. P.O.D. still brings it like nobody's business; Skillet gives you plenty of reasons to bang your head; Shinedown and Korn will sonically pummel you to death if the guys in the pit don't do that to you first; and then there's one of metal's “big four”: Megadeth. Local rock heroes and one of the last remaining bands from the rock-metal hybrid invasion of the late 1990s, Papa Roach (pictured), will also be appearing, as will rock stalwarts Avenged Sevenfold and up-and-comers Halestorm and Five Finger Death Punch. 1600 Garden Highway, www.aftershockconcert.com.
