Formed in Santos with a founding lineup of Marcus Vinicius on vocals, Fausto Pietro on drums, and Vinicius Guedes on guitar, Metallstein draw on old-school death metal, speed/thrash, and grindcore for a raw and uncompromising sound. The band released their self-titled debut single containing six tracks in early 2023 and have since appeared on the 'Workingclass In Roll – Brazilian Compilation' with the track 'Sonho Súbito'.

A one-person old-school death/black metal project helmed by Terror Holocausto, who handles all instruments and vocals drawing from 90s North American and Brazilian extremity. The debut EP "Before Coffins, Hells and Nightmares" (2021), released through Cianeto Discos, was recorded at Terror Holocausto's own home studio in Bahia and captures a raw, cavernous sound rooted firmly in the early death/black tradition.

Originally founded in Curitiba in the early 2000s, Minatory plays a direct strain of death/thrash with clear debts to Slayer, Death, and Obituary. Their 2002 demo "Spiritual Damnation" drew positive notices from Brazilian metal press including Rockbrigade and Whiplash, establishing the band as a fixture of the southern underground scene.

Misanthropy blends the heaviness of death metal with the atmospheric melancholy of gothic metal, crafting a sound rooted in themes of death and inner torment. Hailing from the Amazonian city of Santarém, the band later continued under the name Inner Sigh, carrying forward their emotionally-charged approach to extreme metal.

Monasterium was a death/doom/gothic metal band from Teresina active in the late 1990s, releasing the full-length "Innocent Rise" on Demise Records in 1999 and a demo titled "Inviolable" in 1998. Their sound blended the heavy melodic sensibility of gothic doom with death metal weight, placing them among the more ambitious extreme acts to emerge from the Piauí underground.

Moonlight Scream began in 2012 playing death/black metal with themes of love and sorrow before pivoting toward an atmospheric, largely instrumental post-black metal sound in their later years. After a hiatus, the project resurfaced and eventually evolved into new incarnations — Ócio and then Passional — reflecting a continuous drift away from aggression and toward texture and mood.

Morbid Butcher were a death/black metal band from Espírito Santo whose roots trace back to the late 1980s underground tape-trading circuit, releasing demos such as Randiness of God (1988) and The Dark Plague (1994) before returning with Morbid Butcher Return (1998) and Fly for Darkness (1999). Their live album Muggefug (2006) served as a document of the band's raw, primitive approach before they eventually dissolved.

Morbid Devourment are a death/thrash trio from Brasília who consciously root their sound in the primitive filth of early-80s metal, citing Venom, Hellhammer, and Bulldozer as touchstones. Their 2025 debut EP Deathstrike Rebellion packs nine songs into eighteen minutes of raw, occult-themed extremity, following earlier singles that established the band's violent aesthetic.

Mordrom is a continuation of Crux Cullum, a band that ran from 2007 to 2016 before being resurrected under this name in 2024. The project blends death metal with thrash and black metal undercurrents, channeling themes of occultism, misanthropy, and anti-religion, with the album "Walking to Bloody Death" representing their current direction.
