Las Vegas-bred rockers Adelitas Way burst onto the hard rock scene in 2009 with their self-titled debut and the anthem 'Invincible,' which became a staple on ESPN and WWE programming. Frontman Rick DeJesus leads the band through arena-ready hooks and muscular guitar tones that draw from post-grunge and alternative metal traditions. Their consistent output of radio-friendly yet hard-hitting rock has kept them touring relentlessly across the US festival circuit.

The godfather of shock rock, Alice Cooper has been theatrically terrorizing audiences since forming his first band in Phoenix, Arizona in 1964. From the proto-punk fury of 'Love It to Death' and 'Killer' through the glam-metal resurgence of 'Trash,' Cooper's guillotine-wielding stage shows and darkly witty songwriting defined the very concept of rock-as-horror-theater. His influence stretches from KISS to Marilyn Manson, and his live performances remain elaborate spectacles of vaudeville and macabre.

Santa Cruz, California's American Adrenalin deliver high-octane rock fueled by adrenaline-pumping riffs and anthemic energy. The band brings a straightforward, no-frills hard rock attack that channels the spirit of California's punk and rock scenes into a modern, aggressive package.

Austin, Texas three-piece American Sharks blast through a high-octane hybrid of punk, stoner metal, and pop hooks that sounds like Weezer collided with a monster truck. Since their 2013 self-titled debut, frontman Roky Moon has led the band through relentless touring alongside heavyweights like GWAR, Clutch, and Red Fang. Their riff-driven approach strips away pretense in favor of pure, sweat-drenched rock and roll energy.

Orange County's Atreyu helped shape the metalcore landscape of the early 2000s with their dual-vocal attack and melodic sensibility on albums like 'The Curse' and 'A Death-Grip on Yesterday.' Named after the hero of The Neverending Story, the band's anthemic choruses and Alex Varkatzas's fierce screams made them staples of the Ozzfest and Taste of Chaos touring circuit.
