The Trespass America tour infiltrates the outdoors of the Time Warner Cable Uptown Amphitheatre with a lineup of seven metal bands determined to slay the crowd with an arsenal of acoustics. Five Finger Death Punch guitarist Zoltan Bathory promises the event to be “a theme-park thrill ride for metalheads.” Zoltan’s slashing riffs and indefatigable guitar needling powers his band through their latest album, American Capitalist. Its antagonistic, come-at-me anthem “Back for More” soundtracks the digital gridiron battle in Madden NFL ‘12, as well as Knucklehead fans’ morning battle for cleanliness in the shower.

Killswitch Engage gets back on the stage with its original vocalist, Jesse Leach, the frontman who rocked 2002’s Alive or Just Breathing. After dates in Europe, Trivium returns stateside to tout In Waves, the latest album in which metal’s horizons were broadened by layering the genre’s signature sound with fire extinguishers, cardboard tubes, and other unlikely instruments. Four hundred shows in two years have hardened Pop Evil into grizzled road warriors who sing about the “hell on heels” that is “Boss’s Daughter.” Battlecross, God Forbid, and Queens outfit Emmure will also take the stage to keep heads banging and practice heralding the apocalypse.

Due to security restrictions, G-Passes must be printed out and presented in person at the event. They cannot be redeemed through the mobile app.
