A ritualistic project fusing black metal ferocity with the suffocating weight of doom, Malaise Shire conjures dense atmospheres rooted in darkness and despair. Their 2022 release "Painful Ritual of Despair" showcases a brooding blend of tortured riffs and ceremonial dread, recorded entirely in Paraíba.

Taking their name from the infamous 15th-century witch-hunting manual, this Belo Horizonte outfit channels the sinister crossroads between black and death metal with a sound rooted in darkness, blasphemy, and extreme aggression. Operating from one of Brazil's most historically fertile metal cities, Malleus Maleficarum carry forward the traditions of the Minas Gerais extreme underground.

Mass of Souls combine black metal bleakness with gothic doom atmosphere, drawing clear influence from Candlemass — their self-titled demo even included a cover of the Swedish legends' "Solitude." The project surfaced in 2019 with the single Tales of a Rebel Soul, establishing a sound that sits at the darker, more sepulchral end of the doom spectrum.

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.

Morbid Desecration deal in war metal — raw, punishing black/death metal built around themes of war, apocalypse, and annihilation, in the tradition of Brazilian bestial metal. They have been releasing material since 2016 on the underground circuit, operating with the ferocity and no-frills production that defines the genre.

Morbid Perversion channel the spirit of Brazilian extremity — Sarcófago, Sex-trash, Holocausto — through a bestial black/death metal attack soaked in sadism and anti-religious perversion. Founded by guitarist/vocalist Sexxxtrash and drummer Lunatic, the band spent a decade releasing tapes and 7" vinyl before collecting that material on the 2021 retrospective Morbid Skills of Evil (A Decade of Desecration), followed by Infamous Dogmas of Sacrifice in 2023.

Morbosus is a Buenos Aires black/death metal duo founded in July 2012 by guitarist Burner of the Cross and vocalist/drummer Infernal Commando Necromansy, drawing primary influence from the raw South American extreme metal of Sarcófago, Vulcano, and early Sepultura. The band released their debut album Black Death Commando in September 2014, a five-track record steeped in themes of Satanism and blasphemy.

Morbus Sacer plays a raw, uncompromising hybrid of black and death metal rooted in the South American underground tradition. Their 2017 demo, Demo MMXIII, was released on cassette through Aurora Australis and delivers four tracks — Iron Cleaves, Obliteration, Salve of the Enervated, and Non Serviam — with a crude, hostile production that suits the material.

Active since the early 2000s, Morcrof weaves black and doom metal through a lens of occultism, mysticism, and existential philosophy, with Latin and Hebraic titles underscoring the band's esoteric leanings. Their 2005 full-length "Machshevet Habriá (Myths and Conjectures of Creation)" stands as a cornerstone of their catalog, and they have remained prolific into the 2020s with releases including the 2022 full-length "De Pessimism Philosophiam et Dogma Nihilistic."
