Their live album Muggefug (2006) served as a document of the band's raw, primitive approach before they eventually dissolved.

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.

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.

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.
