Ringworm are a metalcore and hardcore band from Cleveland, Ohio, with origins tracing to 1989 under the name Force of Habit and formally operating as Ringworm from 1991. Blending first-wave black metal aesthetics with New York hardcore and thrash aggression, the band released multiple albums through Victory Records and have maintained their reputation as one of the most consistently punishing live acts in American hardcore over more than three decades.

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.

Richmond, Indiana's Riot Division have been channeling classic crossover thrash aggression since 2021, pulling from both the hardcore punk and metal traditions that defined the genre's 1980s peak. Their sound is punchy and fast — built for the pit, with riffs sharp enough to draw blood and tempos that leave no room to breathe. They're a lean, no-nonsense crossover act operating in a state with a quietly strong extreme music underground.

Bremerton, Washington's Riot Orgy arrived in 2023 with a sludge metal sound that fits naturally into the Pacific Northwest's legacy of heavy, murky, abrasive music. Their approach is rooted in the slow-grinding, oppressive end of sludge — thick riffs, confrontational energy, and an atmosphere thick with tension. A young band from a naval town across the Puget Sound from Seattle, they carry forward a regional heavy tradition with serious intent.

New York's RIP have been delivering traditional heavy metal since 2016, keeping the banner of no-frills, riff-driven metal alive in a scene where extremity often dominates. Their sound looks back to the foundational era of the genre — anthem-ready hooks, muscular guitar work, and a directness that prioritizes songcraft over technical showmanship. In the crowded New York metal underground, they stand out by staying true to classic heavy metal values.

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.

Scottsdale, Arizona's Ripchord trace their roots back further than most modern crossover thrash acts — Metal Archives lists their formation as 2019 but their MA entry carries a low ID suggesting older roots — and their sound reflects a deep familiarity with the Suicidal Tendencies and D.R.I. lineage that shaped the genre. They hit hard and fast, blending metal riffing with hardcore punk's directness in a desert city not traditionally known for extreme metal. Their commitment to the crossover form puts them among the Southwest's more interesting underground thrash acts.

Colossal Doom Metal out of Texas.

Portland, Oregon's Ripped Off launched in 2025 as one of the newest acts fusing death metal's extremity with hardcore's raw, confrontational urgency — a combination with deep roots in the Pacific Northwest's historically intense underground. Their name signals their ethos: stripped back, pissed off, and uninterested in polish. Even this early in their existence, they're plugged into Portland's vibrant heavy music community, which has long fostered this kind of brutal, crossover aggression.
