Lord Devastador is an Ecuadorian black/death metal solo project with roots stretching back to Quito in 1996, when it was active as a band before disbanding in 2000 and relaunching as a one-man outfit. The project's 2014 release "Infernal Holocaust" compiled two unreleased demos from 1998 and 2000 with remastered sound, showcasing a raw, Deathrashing Metal style sung entirely in Spanish.

Lucifer's Doom is a black/doom metal band from Rio de Janeiro, Brazil, active since 2015. The band released a self-titled EP in June 2015, a three-track CDr debut that blends avant-garde black metal atmospherics with mournful doom sensibilities. Their sound features high baritone vocals over heavy, slow-burning riffs with lyrical themes drawn from Christian eschatology.

Lábar'Oculto is a black/doom metal band from Piraju, São Paulo, formed in 2017, whose lyrics draw on poetry, literature, and occultism. The band released their self-titled debut album in 2020 through Misanthropic Records and Black Hearts Records, recorded at Amarello Sound Studio between 2017 and 2019. The album was preceded by the single Lábar'Oculto (Contravulgata) and a live recording from UMF XVIII.

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.

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 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.
