A death metal trio featuring Necromayhem Ferethrum on vocals and guitar alongside André Burns and Bernardo Exhumator, whose 2023 debut EP 'Endless Nightmare' announced a firm commitment to old-school death metal ugliness. The six-track record was recorded and produced by Burns at Cave Studio and leans into the putrid, cavernous sound of the genre's earliest era.

Necrovisceral blend brutal death metal ferocity with black metal atmosphere, hailing from the Amazonian city of Manaus. Their Bandcamp catalogue includes the release Pandemia Apocalíptica, showcasing a grinding, aggressive approach rooted in the South American extreme metal underground.

Necrovomit 666 is the one-man project of Victor Skullcrusher, beginning in raw black metal territory with the 2023 debut Death to Mankind before rapidly expanding into black/death and grindcore on a string of releases including Witchcraft and Blood, Satanic Slaughter, and splits with acts like Amorth and Satanic Empire. The project moves with relentless prolificacy through the most bestial corners of extreme metal, steeped in blasphemy and sonic ugliness.

Necrowar have been grinding out death-thrash metal from the outskirts of Rio de Janeiro since 2004, building a catalogue that includes the early Blood War EP and the full-length All Trajectory, released in 2019. Their music channels the war-themed aggression of classic Brazilian extreme metal, with lyrics centering on geopolitical conflict and social struggle.

One of the most ferocious products of the late-1980s Brazilian underground, this Minas Gerais quartet — led by vocalist/guitarist Deathvomit alongside Rotten on bass and Rotten Corpse on drums — recorded the 1988 demo "Brutal Mutilation," a cassette-only release celebrated for its catastrophic rawness. The demo was reissued decades later as an LP through Nuclear War Now! Productions, cementing its cult status.

A veteran deaththrash outfit originally assembled in the late 1980s and documented by the 1987 demo "Insane Mutilation," drawing heavily from the aggressive edge of Kreator, Slayer, Celtic Frost, and Venom. After a long dormancy the band returned to activity and released the EP "The Evil Never Dies" through Oliver Discos, reaffirming their commitment to old-school extremity.

Formed in the late 1980s, Necrópsia began as a raw death metal act before shifting toward thrash and ultimately hard rock, charting an unusual evolutionary arc across a handful of years. Their early work survives in two demos, "Vozes do Necrotério" (1989) and "The Final Abyss" (1992), which document the band at their most extreme.

Nefarious Abyss is the solo project of multi-instrumentalist Dominus Gargoyle, conceived as a complete audiovisual experience built around a fictional dark kingdom. The 2019 debut album Dominus blends atmospheric, melodic, and symphonic black metal across ten tracks, drawing listeners into an elaborate personal mythology of conquest and darkness.

Nefarious Exterminium is a Death Metal band from Bogotá, Colombia, formed in 2024. The band released their debut full-length "After the Perverse Act" in April 2025 through Ácido Music Studio, an eight-track record built around themes of violence, perversion, and chaos.
