Dallas heavy trio fusing drone, doom, post-rock, noise, grunge, and classic metal.

San Antonio avant-metal trio weaving post-hardcore, noise rock, and dark post-rock.

Named after the bone-devouring deep-sea worms, this McLean, Virginia trio crafts atmospheric sludge/doom/post-metal built around sprawling, longform compositions that open with post-metallic calm before collapsing into harrowing dual vocals — haggard Neurosis-style yells alongside creature-like shrieks — backed by black metal blast beats and cavernous low-end. Their 2020 album Meridians pushed further into drone and ambient minimalism, cementing their reputation as one of the more adventurous acts in the American atmospheric sludge underground.

Chicago's The Swan King craft music at the junction of stoner metal's fuzz-soaked riff worship and post-metal's expansive, textural reach, building songs that alternate between narcotic groove and patient, building intensity. Formed in 2012, they draw from the deep well of Chicago's heavy and experimental underground.

Brooklyn's Thera Roya traffic in heavy, slow-burning sludge and post-metal, building suffocating walls of sound from a base in New York City's underground scene since 2013. Their music favors atmosphere and weight over speed, with extended compositions that grind and drift in equal measure.

Formed in New York in 2022, This Is the Last Time work in progressive and post-metal territory, building lengthy, texture-driven compositions that prioritize atmosphere and emotional weight over technical showcase.

Tallahassee, Florida's Threshing occupy the slow, suffocating overlap between sludge, doom, and post-metal, constructing oppressive walls of distortion that sag under their own weight — a sound shaped as much by Southern heat as by heaviness.

Thumos, active since 2018, work the intersection of progressive doom and post-metal with a measured, philosophical approach — their name drawn from the classical Greek concept of spirited passion — building expansive compositions that reward patient listening.

Eau Claire, Wisconsin's Thunderlung operate in the ambitious space between sludge, post-metal, and progressive metal, constructing layered, slow-building compositions that reward patient listening. Founded in 2018, they bring an Upper Midwest sense of space and patience to music that can shift from suffocating heaviness to expansive, textural passages within a single track.

Out of Westchester County, New York since 2017, Thunderon blend the hazy low end of stoner metal with the atmospheric reach of post-metal, crafting music that drifts between weighted groove and more expansive, effects-laden territory. Their suburban New York origin gives them a certain restless edge that keeps the music from settling too comfortably into either genre.

Austin's Tibetan Sky Burial fuse blackened savagery with the wide, contemplative sweep of post-metal, drawing on funerary imagery and drone-laden atmospherics. The project formed in 2020 and occupies the bleaker, more ritualistic corner of the Texas experimental underground.

Providence's Tides trade in atmospheric sludge and post-metal, building slow-burning compositions that favor emotional weight over brute force. Since 2014 the band has cultivated a sound rooted in dynamic tension, moving between quiet dread and dense, wall-of-sound crescendos.

Brooklyn's Tombs are one of the most distinctive voices to emerge from the New York underground, layering post-metal's expansive atmosphere over black metal's bleakness since 2009 to create dense, emotionally charged records that transcend both genres.

Phoenix, Arizona's Torment of Gloom, formed in 2020, combines doom, sludge, and post-metal into slow-burning, heavy-atmosphered soundscapes. The oppressive desert heat of their city seems to seep into their thick, suffocating sonic palette.

Frederick, Maryland's Trap Ratt are a very young sludge/post-metal act formed in 2024, dragging heavy atmospheric texture through slow, distorted riffing and building the kind of oppressive post-metal architecture that rewards patient listening.
