Necropyre is a Death/Black Metal band from Ecuador, active since 2021. Their self-titled "Demo I," released in July 2021, features four tracks of raw extreme metal written and performed entirely by the band, with all music and lyrics credited to Necropyre. The demo was self-released independently on Bandcamp under the straightforward descriptor "Metal from Ecuador."

Negativus blends old-school death metal with groove-laden heaviness, drawing on the sounds of Obituary, Entombed, and Celtic Frost while writing all their lyrics in Portuguese. Their 2024 debut "Detestabilis" features vocalist Eduardo Jarry alongside guitarist Thyago Trajano, bassist/guitarist Victor Hugo Targino, and drummer Eduardo Amorim, delivering ten tracks of punishing, mid-paced brutality.

A solo death/black metal project launched in 2023 by veteran musician Fábio Nosferatus Lima, who has been active in the Brazilian underground since 1994. Drawing on horror-film obsessions, his releases — including Chainsaw Massacre, Deus-Verme, The Exorcist, and Conjured — explore a grimy intersection of death metal brutality and black metal atmosphere rooted in exploitation-cinema imagery.

Nuclear Screams traffic in a dense blend of death, thrash, speed, and melodic death metal that leans heavily on aggression without abandoning hooks. Their debut EP A Path to Endless Days arrived in November 2021, and the full-length Human Frailties followed in 2025, both recorded in Minas Gerais and showcasing a band comfortable moving between brutal riffing and more atmospheric passages.

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.
