Louisville's Mayhem has been fusing death and thrash metal since 1987, a full decade into the genre's formative years, making them one of Kentucky's longer-running extreme metal acts. Their Bandcamp presence keeps a low profile, but the longevity is undeniable.

Portland's Mayhem launched the same year as their Louisville namesake — 1987 — and has spent nearly four decades channeling heavy and thrash metal through the Pacific Northwest's dense, damp energy. They're a genuine relic of the pre-internet regional underground.

After leaving Underoath, Dallas Taylor formed Maylene and the Sons of Disaster to pursue a grittier blend of southern metal, hardcore, and outlaw country that owed as much to Lynyrd Skynyrd as it did to Norma Jean. Albums like 'II' and 'III' deliver whiskey-soaked riffs and Taylor's distinctive growl over a foundation of swaggering, dirty southern grooves.

Springfield, Massachusetts's Maze of Maze carves through the space between black and death metal with a relentless, disorienting intensity. Since 2017, they've built a sound that feels as claustrophobic as their name suggests.

Formed in St. Louis in 2021, MCF brings a lean, aggressive thrash attack to the Midwest with an ear for the classic Bay Area blueprint. Their sound is built on tight riff work and a no-frills urgency that cuts straight to the bone.

Millions of Dead Cops. Austin political hardcore punk, one of the most important punk bands in Texas history.

Rising out of Clinton Township, Michigan in 2023, MDCLXV — a name rendered in Roman numerals — channels the cold, suffocating atmosphere of second-wave black metal into a distinctly modern American framework. Still early in their existence, they carry the intensity of a project with something to prove.

Los Angeles-based Me Igi traffics in raw black metal stripped down to its most abrasive essentials, formed in 2021 against the grain of the city's sunlit reputation. Their material is lo-fi and confrontational, drawing from the primitive necro tradition while filtering it through a Southern California isolation.

Denver's Mead Thief blend heavy doom with the muscle of classic heavy metal, evoking mile-high altitude and long, barren stretches of highway in equal measure. Since forming in 2020, the band has leaned into slow, crushing riffs anchored by a traditional songwriting sensibility that keeps the hooks in reach.
