A long-running death-black metal force from the São Paulo underground, Malediction 666 draws heavily from the Greek black metal tradition — the 2019 album "We, Demons" even features guest appearances from Necroabyssious of Varathron and Sakis Tolis of Rotting Christ. The project is largely driven by a single individual, resulting in a focused and consistent sound shaped by decades of devotion to the dark arts.

Maleficarum brings a psychedelic sensibility to black metal from the scorched northeast of the country, threading hallucinatory textures through an otherwise bleak and hostile framework. Their 2021 release "Blocksberg Selecta" serves as an entry point into their occult-influenced sound, which sits at the intersection of ceremonial atmosphere and raw black metal abrasion.

A fresh entry into the Brazilian raw black metal underground, Malefício operates in the harshest and most primitive end of the genre spectrum, embracing lo-fi production as an aesthetic weapon rather than a limitation. The project launched in 2024 and channels a relentless hatred through minimalist, corrosive songwriting.

Males Fecundos was a Brasília grindcore outfit with members drawn from other local extreme metal projects, channeling social fury and disgust with human mediocrity through blunt, fast-as-possible attacks in the tradition of Napalm Death and Agathocles. Their short run produced a debut EP before the band dissolved.

Malevolente is a one-man extreme metal project from Bogotá, Colombia, founded in 2021. Operating as an independent solo effort, the project draws on a wide range of metal subgenres with the goal of crafting a distinctive musical identity, releasing a series of Spanish-language singles and EPs including the seven-deadly-sins-themed Mater series and the 2026 release Anhelo.

A traditional heavy metal outfit from Sorocaba, São Paulo, Maligna operated within the classic mold of melodic riffing and anthemic song structures before disbanding. Their work reflected the enduring influence of 1980s heavy metal on the Brazilian underground circuit.

Malignant Excremental deliver gore-soaked death metal out of Cuiabá with clear debts to Autopsy and Necrony, reveling in slow-churning, putrid riff work alongside bursts of brutal speed. Their 2022 debut full-length "Descrição Explícita e Brutal da Face da Morte," released through Rotten Foetus Records, established them as one of the more authentically fetid death metal acts to emerge from the Midwest region of Brazil.

Rising from the hot interior of Piauí, Malignitude play a rawly atmospheric strain of black metal with occult and misanthropic leanings, as heard on their debut "Sons of Infernal Land." The record unfolds across six tracks of cold, mid-paced aggression, channeling the bleak grandeur typical of Scandinavian second-wave black metal through a distinctly northern Brazilian lens.

Malignus Morttvss is a singular one-man project that began in raw black metal territory before mutating into a deliberately abrasive collision of noise and goregrind, self-released through the project's own MASMORRA Independent imprint. Albums like "WHITENOISE" and "FUCK LOVE" reveal an artist more interested in sonic provocation and controlled chaos than genre conventions, operating entirely outside the mainstream underground.
