Probot is the brainchild of Dave Grohl — a sprawling heavy metal superproject that united some of the most iconic voices in underground metal history, including Lemmy Kilmister, Max Cavalera, Wino, and members of Discharge and Sepultura. Operating out of Alexandria, Virginia and drawing from doom, stoner, groove, and classic heavy metal, the project stands as a reverent and thunderous love letter to the genres that shaped Grohl long before Nirvana.

Fort Myers, Florida's Psychic Dose traffics in psychedelic stoner-doom — slow, narcotic riffing saturated in fuzz and reverb, evoking sun-scorched Southern haze with a heavy, lysergic weight that builds across their songs.

A freshly formed doom and stoner metal act out of Milwaukee, Wisconsin, Psychic Shiv emerged in 2025 wielding the Rust Belt's blunt force through heavy, slow-burn riffs and a crushing low-end that anchors their nascent sound.

Scranton doom and stoner metal band born in 2022, stacking fuzzed-out riffs and tar-slow tempos in the tradition of the Northeast's working-class heaviness. Their name alone signals a commitment to lung-collapsing low end.

Bayonne, New Jersey's Pyre Fyre marries sludge metal's tar-thick heaviness to stoner metal's hazy, fuzz-soaked grooves, forming a swamp of heavy riffs and slow-burning momentum that leans hard into the oppressive and the hypnotic since their 2021 formation.

Fort Worth's Realm Drifter crawled out of the Texas heat in 2022 dealing in stoner-doom that stretches riffs into long, resin-thick passages and anchors them with the weight of the Lone Star sun. It's psychedelic, slow, and heavy in the way that only bands steeped in the Texas desert-rock tradition manage.

Thunderous Stoner / Sludge Metal from Plainview.

Long Beach, California's Red River Massacre trade in sludge-soaked stoner metal that bakes in Southern California's sun-bleached intensity and the corrosive weight of the city's underground. Since 2018, they've pursued a slow, oppressive heaviness that owes as much to Southern sludge tradition as it does to desert-rock psychedelia.

Pueblo, Colorado's Rendlesham take their name from a famous UFO incident and match that cosmic mystery with stoner metal that lumbers and levitates in equal measure. Since 2015 they've been Pueblo's heavy ambassadors, building riff-worship around fuzz-drenched guitars and an unhurried, planet-rolling heaviness. Equal parts desert and outer space.

Deltona, Florida's REO RapeVan merge sludge and stoner metal into something swamp-thick and deliberately abrasive, fully committed to the underground's most transgressive naming traditions. Formed in 2020, they lean into the lo-fi, mean-spirited corner of the sludge spectrum where Eyehategod's shadow falls longest. Florida's heat and humidity seem baked into every slow-motion riff.

Groove-driven stoner metal from Austin.

Sioux Falls, South Dakota's Rifflord have been immersed in the doom/stoner universe since 2015, building the kind of riff-centric, low-frequency heavy music that prioritizes crushing weight over technical complexity. South Dakota's vast, flat landscapes lend themselves naturally to slow, expansive music, and Rifflord's weed-scorched tempos and hazy guitar tones feel suited to long, empty stretches of prairie highway. They're a testament to the fact that America's forgotten middle can produce music as heavy and unhurried as anywhere else.

Ringing Bell emerged from Urbana, Illinois in 2024 as a new entry into the fertile American sludge/stoner/doom underground, layering tar-thick guitar tones over slow-burning, feedback-drenched compositions. Their sound sits at the intersection of psychedelic drift and heavy punishment — the kind of music that moves like molasses and hits like a wall. As a brand new band, they represent one of the freshest voices in the Midwest's heavy underground.

Nashville's Rintrah has been cultivating a heavy, psychedelic doom sound since 2014, drawing from both the serpentine riff traditions of stoner metal and the meditative weight of doom. Metal Archives classifies them under psychedelic doom and stoner rock, and that breadth is audible — their music tends toward atmospheric, slow-rolling explorations rather than blunt force. In a city dominated by country and roots music, they represent something darker and heavier bubbling beneath the surface.

Grand Rapids, Michigan's Rip VanRipper have been rolling through the stoner metal and rock underground since 2015, building a sound defined by fuzzed-out riffs, laid-back grooves, and a hazy, road-worn attitude. Their name is a playful nod to their approach — heavy but loose, napping between riffs before snapping back to life with a crushing passage. They're a reliable presence in the Midwestern stoner metal circuit, with years of work to back up their reputation.
