Martyrdom have spent decades honing a suffocating brand of death/doom rooted in occult and ancient civilizations imagery, with slow, mournful riffs giving way to cavernous death metal blasts. After a 1997 demo and years of obscurity, they released the EP "Culto Primitivo à Morte" in 2017 and their debut full-length "Ritual Místico de Adoração à Sabedoria Ancestral" in 2018, recorded at Netuno Estúdio and mixed in Montreal.

Mausoleum were a death/black metal outfit from São Paulo whose lyrical themes circled around paganism and occultism, a common thread running through releases spanning compilations such as "Southern Warriors Cult #1" (1999) and "War... Satanic Victory!!!" (2003). Their output also included "10 Anos de Bestial Massacre" in 2004 and "O Retorno à Batalha" in 2006, cementing a two-decade presence in the Brazilian underground before the band eventually dissolved.

Mediadhor hit the ground running with two releases in quick succession: the demo "Caminho do Arrependimento" in late 2016 and the full-length "Campos Mortais" in early 2017. Their approach fuses the grinding aggression of death metal with thrash's rhythmic momentum, giving the material a relentless, forward-charging quality.

Rooted in the South American underground, Mephistopheles play a morbid amalgam of doom, death, and black metal drawing from the same unholy lineage as Mystifier, Sarcófago, and Blasphemy. Their two early demo tapes — 'The Prophecy' and 'Black God' — were later compiled and released on CD by Voz da Morte Prod in 2018 as 'The Prophecy of Black God,' preserving eleven tracks of raw, English-language ritual extremity.

Mephitic Tomb is a raw death/black metal project steeped in the pestilential South American underground tradition, channeling blasphemous hostility through a sound informed by anti-religious and Cthulhu Mythos themes. Formed in 2024, the project draws on the volatile heritage of the region's extreme metal underground, producing tracks such as 'Cursed by Coffin Joe' and 'Leather, Chains, Hooks, Sex' with uncompromising ferocity.

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.
