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. The remote Colorado mountain town setting feels appropriate for music this expansive and cold.

Phoenix's Thra formed in 2019 and occupies a brutally claustrophobic corner of extreme metal where blackened sludge, death metal, and black metal collide under the Arizona desert heat. The result is dense, punishing, and unrelenting — music that reflects the scorched harshness of the Southwest landscape.

Washington State's Thrain have been cultivating their black metal sound since 2013, operating in the Pacific Northwest underground with the cold, raw intensity the region's climate seems to inspire. The band keeps a deliberately low profile, letting the music — bleak, uncompromising, and rooted in black metal's traditional vocabulary — speak for itself.

Portland, Oregon black/thrash outfit formed in 2020, combining the cold, malevolent atmosphere of black metal with the kinetic aggression of thrash — a pairing the Pacific Northwest underground has shown particular affinity for in recent years.

Providence, Rhode Island black/thrash act formed in 2019, fusing occult black metal menace with the speed and directness of thrash from a city that has long nurtured dark and extreme underground music, adding a witchcraft-inflected edge to their sound.

A black metal act out of Nashville, Tennessee, Threnodian emerged in 2020 with a sound steeped in raw, cold aggression typical of the American underground. Their name — evoking funeral songs — hints at a mournful, harrowing approach to the genre.

Formed in 2023 in the Bay Area underground, Oakland's Threnodist blends black metal's corrosive intensity with shoegaze's hazy, immersive textures, creating a sound that is simultaneously abrasive and dreamlike.

Milwaukee's Threnody deal in atmospheric black metal, weaving bleak, expansive soundscapes from the flat midwestern darkness — a project that has been unfolding since 2012 with a cold, meditative intensity.

Brooklyn's Throaat have been one of New York City's more ferocious underground exports since 2013, mashing speed, thrash, and black metal into a filthy, relentless hybrid that strips away any pretension in favor of raw, primordial attack.
