Lignum Mortis is a one-man black and doom metal project from Valdivia, in southern Chile, that merges sounds drawn from death metal, black metal, and dark ambient to create densely layered sonic landscapes. The project's self-titled debut was released in 2015 as a limited CD-R run of 30 copies before being made available digitally, followed by Vacuum Inferno in 2022 and Lignum Mortis II in December 2025. All music, recording, mixing, mastering, and artwork are handled entirely by the sole member.

Nigurah blend the groove-heavy stomp of mid-era Sepultura with thrash and death metal aggression, arriving from the same Rio Grande do Sul scene that has long punched above its weight in Brazilian extreme metal. The quartet — Rafael Prado on vocals, Fernando Cezar Jr on guitar, Felipe Ribeiro on bass, and Luke Santos on drums — released their debut EP "Incendiar" in October 2020.

Nihilifer is a death/black metal band from Temuco, Araucanía, that emerged in 2013 from earlier projects Sarcoma Corpus and Ritualism, signing to Throats Productions. The band released the demo Chaos Ex Nihilo in November 2013 and the full-length Subterfacto.declive in 2018, a dense 54-minute album exploring themes of occultism, anti-creationism, and spirituality across eight tracks.

Self-described as "deadly corrosive crossover," this Brasília five-piece — led by vocalist Lauro "Zapata" and guitarist Gabriel "Zenön" — released their debut full-length Corrosive Hatred in November 2021, a ten-track assault recorded at Texas Studio. The record blends thrash riffing with hardcore-punk velocity and a powerviolence-adjacent ferocity, with tracks like "Destroy the State" and "Underground is Not a Competition" making the band's antagonistic stance explicit.

One of the pioneering female-fronted grindcore acts in Brazil, No Sense from Santos made an early mark with the "Out of Reality" EP and the full-length "Cerebral Cacophony" (1992, Cogumelo Records), led by vocalist Marly with blistering bursts that drew comparisons to Napalm Death's early violence. After disbanding in the 1990s, the band reunited and released the comeback album "Obey" (2011), bringing the original lineup back to a style rooted in madness, social alienation, and pure grindcore aggression.

Nocthun describes their music as "apocalyptic antifascist metal," channeling blackened death metal into explicitly political and confrontational themes. Their debut full-length "Rest in Flames" establishes the project with tracks like "In the Uncanny Valley of Death" and "Volcanic Hellfire," pairing blast-driven aggression with ideological conviction.

Nocturnal Bleed play old-school death metal with a raw, unpolished ferocity rooted in the Floridan and Swedish traditions, releasing the debut full-length Lake of Fire in 2024 — a ten-track assault spanning short blasts like "Morbid Whisper" through to lumbering cuts like "Planetary Slavery" and "Devour the Corpse." The record was preceded by the 2023 single "Scourge of Pain," establishing the band's place in the Pará underground.

Nofek are a death metal trio from Bertioga whose recorded activity dates to the mid-2000s, issuing the demos Os Sete Flagelos in 2004 and Golgota in 2006. The consistent lineup of Douglas Liberato on vocals and guitar, Márcio on bass, and Carlão on drums has persisted across the band's long underground existence.

NoxEternum is a black/death metal band from Alto Paraná, Paraguay, active from 2022 until their split-up. In their brief existence they were prolific, releasing two full-length albums — "Portal to NoxEternum" and "The Black Window of the Mind" — along with two singles, all in 2022.
