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.

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.

Nefastus is a death metal band from Formosa, Argentina whose self-titled debut EP, released in 2023, drew notice from Metal Forces Magazine for balancing brutality with melody across five tracks. Drummer Ives Lescano's work was specifically highlighted in that review, with tracks spanning from thrashy direct assault to more technical mid-tempo arrangements.

Born from members of Disfigured By Hatred, Nefärioüs D-saster channel the raw fury of Anti Cimex and D-beat punk through a death metal filter on releases like the 2018 Worship Disaster EP and the 2018 split Total Disaster. Their sound is a deliberately abrasive collision of nuclear-age dread, war imagery, and underground punk nihilism.

Negative Delusion deal in straightforward old-school death metal rooted firmly in the 1990s tradition, as heard on their 2018 debut album Claustrophobic. The nine-track record leans into claustrophobic riff structures and mid-paced brutality, placing them squarely in the lineage of early Florida and Swedish death metal.

Nekkrofuneral deals in old-school black/death savagery rooted in the Brazilian underground tradition, with Z. Misanthrope on bass and vocals, M. Marra on guitars, and C. Couto on drums. Their 2021 split "A Epítome da Decadência Humana" with Numbomb showcases the band's raw, crust-tinged attack recorded and mixed at Heavy Track Estúdio.

Nekrommander is a one-person black/death metal project helmed by Ghul, whose 2023 EP "Vomiting in Heaven" was years in the making — drums tracked in 2019, the rest completed through 2023. The five-track release blends crunchy old-school death metal with thrash sharpness and hardcore-inflected groove, with session drums contributed by Douglas Batista.
