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.

Morferus is a death metal band from Banfield, Buenos Aires, whose lineup includes vocalist Leandro Cabrera, guitarists Mario Meza and Sebastian Almada, bassist Denis Camacho, and drummer Pablo Meza.

A one-man cosmic death metal project by Paulo Pinheiro Fornazza, known for his work in Fossilization and Jupiterian, Mortal Embodiment channels abyssal, end-of-universe horror through pummeling riffs indebted to Morbid Angel, Dismember, and Disembowelment.

A death metal act rooted in the brutal sound of the '90s Brazilian scene, Mortal Eyes delivered the demo "Extreme Visions" in 2005, a five-track effort blending crushing heaviness with traces of thrash aggression.

Founded by Gustavo Camargo and Flávio Diniz, Mortal Ways weaves science fiction and extraterrestrial mythology into death metal rooted in the traditions of Morbid Angel, Hypocrisy, and Deicide.

Formed in Uberlândia by guitarist Gabriel Tino and bassist Macarrão, Morterror plays straightforward death metal rooted in the genre's fundamentals while drawing on a wide range of metal influences. Their 2021 EP Sertão da Maldição is a four-song cycle built around local horror folklore — specifically the curse-laden deaths of a remote interior settlement called Sertão da Farinha Velha — with tracks like "Sangue Podre" and "Boi Fumaça" translating those dark regional legends into crushing riffs.
