Twinsburg, Ohio's Thou Shalt Not have been a steadfast presence in the Ohio death metal scene since forming in 2000, building a catalog rooted in mid-period American death metal with a commitment to the genre's founding principles.

Based in Steamboat Springs, Colorado, Thousand Year War have evolved over a career stretching back to 2011 from melodic death metal foundations toward an increasingly melodic black metal sound, a trajectory that mirrors similar developments across the American extreme metal underground.

Long Island, New York's Thracian have been crafting their blend of melodic death and thrash metal since 2013, drawing on both the precision of technical thrash and the hook-forward melodicism of the Gothenburg school.
