Assembled during the pandemic in late 2021, O Espírito Profano wrote entirely in Portuguese and drew their themes from death, misanthropy, and spiritual suffering. Their short-lived run produced a self-titled release and a live EP recorded at the UFCAT university festival in Catalão, blending black, death, and doom metal into a dense and despairing sound before splitting up.

Oath of Persistence work in the space where death and thrash collide, building their catalog around Lovecraftian and dystopian themes that run through releases including the demo Deadly Tentacles of Summoning, the album The Myths, and the 2023 EP Arrival. The three-track Arrival tightens their attack into focused bursts, with tracks like "Fear of the Unknown" and "Queen of the Swarm" showcasing the band's appetite for cosmic dread wrapped in grinding riff work.

A São Paulo trio grinding death, thrash, and doom into a single bleak weight, Obsessor channel themes of societal decay and depression through a rawly recorded, underground aesthetic. Their self-released demo material captures a band firmly rooted in the South American extreme metal tradition with no concession to polish.

One of the early extreme metal acts out of São José dos Campos, Obsessos played caustic death/thrash driven by Satanic and occult imagery in the spirit of the mid-1980s South American underground. Their 1987 demo 666: The Ultimate — featuring tracks like "Scream of Priests" and "Satan's Procreation" — stands as a raw document of the era before the band dissolved in 1988.

Emerging from the ashes of 1990s act Lethal Curse, Of the Archaengel blended gothic atmosphere with black and death metal on their sprawling conceptual album "The Extraphysicallia" (2010), a nearly 70-minute work inspired by spiritualist literature and mastered at Sweden's Cutting Room. The album featured guest vocals from Sakis Tolis of Rotting Christ, underscoring the band's ambitions well beyond the local underground.

Overdose Nuclear coined the term "Metal do Mangue" to describe their death/thrash sound rooted in the coastal town of Ubatuba, pairing heavy riffing with socially conscious lyrics about environmental destruction and political corruption. Their 2023 album Metal do Mangue features guest appearances from Mayara Puertas of Torture Squad and Jairo Vaz Neto of Chaos Synopsis, alongside a cover of Raul Seixas's "Cowboy Fora da Lei," cementing the band's distinct identity within the Brazilian extreme metal scene.
