The End A.D. formed in Philadelphia in 2016, fusing the bone-crushing low-end of groove metal with the frantic urgency of hardcore punk.

Their sound channels the blue-collar ferocity the City of Brotherly Love's underground has been producing for decades.

Philadelphia's The Fetals have been weaponizing the thrash-hardcore hybrid since 2009, making them one of the longer-running acts in the city's abrasive underground.

Decades of Philly punk and metal history run directly through their approach.

Phoenix's The Grimm Riffer arrived in 2024 with a death metal and hardcore crossover sound that fits squarely into the desert city's history of producing bands that run hot and hit hard.

As a newly formed act they're still establishing themselves, but Phoenix's active extreme music scene gives them plenty of room to develop.

Moscow, Idaho's The Swelbows attack crossover thrash with the no-frills velocity you'd expect from a band equally indebted to hardcore punk and vintage speed metal, formed in 2013 in a college town far from the traditional crossover hubs. Their music is short, fast, and built for the pit.
