The band has been prolific on wax, with releases including the albums Youth Explosion and Nuclear Awake, and the 2025 EP Touching the Terror appearing on CD, 7" vinyl, and cassette through multiple international labels.

Their 2013 debut album "Press Start to Try Again" features fast, aggressive thrash driven by socially conscious lyrics focused on global crisis and individual agency.

Nadarkhani are a Christian black metal project from Santa Bárbara d'Oeste whose 2021 album Divine Transcendence Supremacy anchors explicitly theological lyrics to a raw, lo-fi black metal framework.

Najash is a blackened death metal band from Posadas, Misiones, whose current lineup includes Alejandro Llanos on vocals and bass, Maximiliano Espachuk and Esteban Rucker on guitars, and Mateo Castillo on drums.

Nameless Gods traffic in doom-death metal built around the contrast between crushing slowness and the aggressive attack of vocalist Malu Sales, whose background includes former São Paulo outfit Sophie's Threat. Their 2024 debut, And That Sigil Meant Death, leans heavily on cosmic horror and occult imagery across seven tracks, with dual guitars from Damien Mendonça and Isabela Ishibashi carving out a sound that prioritizes atmosphere and weight over technicality.

Namroth Blackthorn was a raw black metal act from the northeastern city of São Luís, operating from 2010 until their eventual dissolution. Their output sat within the lo-fi, abrasive tradition of the genre, with lyrical themes rooted in occultism and self-knowledge.

Namuh emerged from João Pessoa in 2021 as a post-black metal project before shifting toward the depressive end of the spectrum in later material.

Naqke is a one-man São Paulo project that pairs raw black metal with dungeon synth, releasing a steady stream of material since 2023 including Old House Memories, Arcadian Tapes I, and The Magicians of Middle Earth. The project shifts freely between abrasive, lo-fi black metal and more solitary, keyboard-driven dungeon synth passages, often within the same release.
