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.

Monasterium was a death/doom/gothic metal band from Teresina active in the late 1990s, releasing the full-length "Innocent Rise" on Demise Records in 1999 and a demo titled "Inviolable" in 1998. Their sound blended the heavy melodic sensibility of gothic doom with death metal weight, placing them among the more ambitious extreme acts to emerge from the Piauí underground.
