Akron's Self Loathing formed in 2018 and operate at the volatile intersection of death metal and hardcore punk, bringing the blunt-force aggression of the latter to the low-end brutality of the former. The band's crossover approach is rooted in the Rust Belt tradition of music that doesn't ask permission — short, crushing, and direct. They're part of a small but committed Ohio underground scene that treats genre boundaries as obstacles to be demolished.

A shadowy Midwestern entity that emerged in 2017, Self Slaughter blend black and death metal in the raw, no-frills manner common to the American underground that operates entirely outside of metropolitan scenes. Their deliberately anonymous presentation — no fixed city listed, a no-frills Bandcamp — reflects a project more interested in creating suffocating extreme metal than building a public profile. The combination of black metal's atmospheric menace with death metal's brutality gives their music an especially oppressive quality.

Pittsburgh's Selfgod arrived in 2022 as a death metal act shaped by Pennsylvania's long history of no-nonsense extreme metal. Rooted in the straightforward brutality of the genre's classic era, they favor punishing riffs and a blunt, unadorned production aesthetic that suits Pittsburgh's steel-and-grime reputation. Still early in their trajectory, they represent a new generation of the city's death metal underground.

Operating under a name designed to provoke, Semen formed in 2015 and pursue a deliberately crude brand of thrash metal that leans into shock value and aggression in equal measure. Their Bandcamp handle — goatsemen — underscores a commitment to the transgressive, scuzzy end of the genre rather than the polished, technically ambitious side. This is thrash as blunt instrument: fast, ugly, and unapologetically low-brow.

Formed in 2020 in Rutherford, New Jersey, Semper Tyrannis bring a progressive and melodic sensibility to death metal, threading complex compositional ideas through the aggressive architecture of the genre. Their approach aligns more with the Gothenburg school of melodic death metal but filtered through a progressive lens that values dynamics, harmonic depth, and structural ambition. They're a notably compositionally minded act for a project still in its early years.

Sempiternal Suffering formed in 2022 and practice raw black metal in the most stripped-down sense — minimal production, relentless atmosphere, and a deliberate rejection of anything approaching comfort or accessibility. The project's name telegraphs its entire aesthetic program: endless, grinding darkness rendered in buzzing, lo-fi black metal that owes more to the Scandinavian second wave's ugliest corners than to any modern polish. Anonymous by design, the music does all the speaking.

Saint Paul, Minnesota's Semtex formed in 2021 and take an explosive approach to progressive thrash, combining the rhythmic intensity and angular riffing of thrash with the structural ambition and harmonic complexity that progressive metal demands. Named after the plastic explosive, their music favors precision over chaos — tight arrangements, shifting time signatures, and a forward-thinking approach that sets them apart from straightforward thrash revivalism. They reflect the technical ambitions that have been quietly flourishing in the Twin Cities metal scene.

Sen Senie Senči emerged in 2019 from Blairstown, New Jersey — a small town perhaps best known to horror fans as the setting for Friday the 13th — and channel that isolated, rural unease into heavy, grinding sludge metal. The Latvian-inflected name suggests a project thinking beyond conventional boundaries, and their sludge operates in the deliberate, punishment-oriented tradition that rewards patience over immediacy. They're a genuinely idiosyncratic act in a genre not short on them.

Rosemead, California's Send Them Sin have been active in the death metal underground since 2013, contributing to the dense and competitive Southern California extreme metal scene with a straightforward, riff-driven approach. Their music sits in the traditional death metal lineage — direct, brutal, and structurally familiar — executed with a commitment to the genre's core values rather than novelty. Over a decade of activity speaks to a resilience and dedication uncommon in the underground.
