Nihtymne is a one-man black metal project from Córdoba, Argentina, created in 2016 by the sole member known as Fóranniht, who handles all instruments, vocals, mixing, and mastering. The project's releases include the demo Wanderings... (2016), the self-titled full-length (2021), and the covers EP The Will To Transgress (2023).

A Christian heavy metal act from Americana who released a split with Jaws called Madman / A Better World in 1995 on Rock Machine Records. The split showcases a straightforward, melodic approach to heavy metal with faith-oriented themes, situating the band firmly in the Brazilian Christian metal underground of the mid-1990s.

Originally active under the name Dunkel from 1997 before adopting the name Ninurta, this Santos-region black metal project released the demo Eternity in Pain through Nocturnal Age Recs in 2003. The band's approach centers on existentialist and philosophical themes, drawing from the raw, confrontational tradition of Brazilian underground black metal.

A solo atmospheric black metal project whose debut EP Sun Kills Every Thing arrived in 2017, blending tremolo-driven riffs with ambient textures and expansive, depressive moods. The project draws on the more introspective strand of the genre, favoring atmosphere and emotional weight over outright aggression.

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.

Formed in Uberlândia with the explicit goal of fusing New York hardcore aggression with thrash metal heaviness, No Defeat released the EP M em M in 2010 and the full-length Escolhas Que Precedem a Conquista in 2012. Vocalist Michel "Padero" anchored their politically charged output, which drew on crossover forebears while addressing social and political themes rooted in Brazilian reality.

No Guerra is an Argentine thrash metal and metalcore band whose album titles — Ahonikenk (2010), Choiols (2012), Weychan (2014), and Traumatica (2024) — draw on the indigenous languages and cultures of Patagonia, including Mapuche and Tehuelche words. After a decade-long gap, the band returned in 2024 with Traumatica, their fourth studio album.

The project of guitarist and vocalist Tiago Torres, a veteran of the Brazilian scene through his work with Mad Dragzter, No More Death channels the fury of Metallica, Slayer, and early Sepultura into a decidedly spiritual framework, with lyrics drawn from the Book of Revelation. Their debut album "The Death is Dead," released in 2025 on Roxx Records and co-produced with Demis Kohler, delivers eight relentless tracks that treat thrash as a vehicle for Christian apocalyptic storytelling.

No One Spoke wove together distorted guitars, live violin, and the lyrical voice of Serbian-Brazilian vocalist Jelena Dobric into a style that deliberately avoided the operatic clichés common to female-fronted symphonic metal, drawing instead on classical and Latin influences. Their sole full-length "Nine Mirrors" (2021) spans nine tracks across forty-seven minutes and includes a guest appearance by bassist Rudy Sarzo on a cover of Ronnie James Dio's "Rainbow in the Dark."
