New Bedford, Massachusetts's Sciomancy — named for the occult practice of communicating with shadows and the dead — have been exploring the darker recesses of sludge metal since 2014. The grim maritime atmosphere of coastal New England permeates their approach, which leans into the genre's tradition of slow, punishment-heavy compositions with an occult undercurrent.

Tennessee's Scion of Ardor formed in 2021 with death metal as their language — a state that has produced a surprising number of genuine underground death metal acts over the years, and this band adds to that tradition with passion and directness. Their name suggests fervent devotion rather than detached brutality, hinting at a more impassioned, emotionally driven approach to the genre.

Los Angeles's Scission have been operating since 2013 at the boundary between metalcore and death metal, a crossover that captures both the precision and brutality of the latter and the structural intensity of the former. In a city as massive and competitive as LA, surviving over a decade in the underground speaks to the genuine quality of their craft.

Gilbert, Arizona's Scissor Dungeon arrive with one of the more memorably absurdist band names in the post-black metal underground, formed in 2022 with a sound that balances the raw, aggressive foundation of black metal with the atmospheric and melodic expansions of the post-black wave. The Phoenix suburban sprawl is an unlikely incubator for this kind of music, making their existence all the more idiosyncratic.

Green Bay, Wisconsin's Scofflaw emerged in 2021 with a sound that fuses the hip-swinging momentum of groove metal with the tightly coiled aggression of metalcore. Their riffs land with a blunt physicality — chugging patterns that lock into a pocket before snapping into breakdowns — while the vocals shift between barked hardcore cadence and abrasive screams. For a young band out of Wisconsin's frozen flatlands, they arrived with a surprisingly seasoned sense of tension and release.

Out of Jonesboro, Arkansas, Scootergypsy has been hauling classic speed and heavy metal influence through the South since 2013 with a no-frills directness that feels ripped straight from the genre's early-80s heyday. Their music runs on twin-guitar attack and wiry, hard-rock swagger — the kind that sounds better on a back-road highway than in a concert hall. They sit comfortably in the tradition of NWOBHM-influenced American speed metal, with enough hard rock looseness to keep it from feeling purely academic.

Formed in 2024 in Wilkes-Barre, Pennsylvania, Scorched Mind arrived already operating at the intersection of three unforgiving genres: death metal's guttural extremity, hardcore's blunt-force confrontation, and sludge's slow, tar-thick grind. That northeastern Pennsylvania post-industrial grit filters through their sound — riffs that drag and then erupt, tempos that punish before collapsing into murk. A brand-new project with the density of something that's been corroding for decades.

Scoria is a thrash metal and crossover band from La Paz, Bolivia, with roots stretching back to 1992, making them one of the longer-running acts in the country's metal underground. The band released a string of full-lengths across the 2000s and 2010s — including Anti-Bolivia (2000), Sol (2002), Resistencia (2004), and Inmortal (2018) — documenting over two decades of politically charged and socially critical Bolivian metal. Their 2021 live album Vive captures the band's enduring presence on the La Paz scene.

One of the longer-running black metal acts in the northern Virginia underground, Fairfax's Scorn has maintained an uncompromising presence since 1992 — outlasting trends, line-up shifts, and the general churn of the American black metal scene. Their output is rooted in the raw, hateful aesthetic of second-wave black metal: tremolo-drenched riffing, blasphemous atmosphere, and a commitment to the form that three decades haven't softened. They remain one of the quiet veterans of the East Coast underground.
