Blending pop-punk hooks with metalcore breakdowns in a way that shouldn't work but absolutely does, A Day To Remember have been Ocala, Florida's most unlikely export since forming in 2003. Albums like 'Homesick' and 'What Separates Me from You' became genre-defining records that bridged the gap between Warped Tour kids and metal fans. Frontman Jeremy McKinnon's ability to pivot between soaring clean vocals and guttural screams became the band's signature.

Madison, Wisconsin's Archers broke onto the scene with a metalcore cover of The Weeknd's 'The Hills' that amassed nearly two million streams, establishing their knack for blending pop sensibilities with heavy breakdowns. Signed to Fearless Records, the band has been dubbed the 'softest bois in metalcore' for their ability to merge pop-punk warmth with crushing metalcore intensity.

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.

Columbus, Ohio's Attack Attack! became the lightning rod of the electronicore movement in the late 2000s, polarizing listeners with their fusion of Auto-Tuned cleans, synth breakdowns, and metalcore heaviness on their debut 'Someday Came Suddenly.' Their crabcore stance became an internet meme, but the band's influence on the intersection of electronic music and metalcore is undeniable.
