Founded in Santo André by Daniel Curtolo and Victor Prospero, Necromesis spent nearly a decade working through an increasingly ambitious run of releases — from the 2009 demo The Dark Works of Art through the EPs Evolving to an Underworld (2011) and Echoes of a Memory (2014) to the full-length The Poet's Paradox (2015) — blending visceral death metal with progressive and thrash underpinnings. The band is also notable as the launchpad for vocalist Mayara Puertas, known as May Undead, who recorded Echoes of a Memory and The Poet's Paradox before departing in 2015 to become the frontwoman of Torture Squad.

A long-running death metal band from the Rio Grande do Sul underground, active since the early 1990s and known for a relentless, gore-infused approach rooted in the old-school tradition. Their catalog spans releases such as "We Work for the Devil," a live document titled "Live Desecrations," and the 2022 full-length "Death to Traitors."

A Curitiba thrash institution that blends guttural vocals with churning riff work and a tightly locked rhythm section, striving for what the band themselves describe as the right balance of speed, weight, and harmonic result.

A short-lived one-man black metal project driven by its sole member Nekrose, channeling themes of melancholy, depression, and internal struggle into nine tracks of emotional intensity on the 2025 album "Inexistencial Inexistência." The band dissolved the same year the album was released.

A self-described "old school death metal fleshcult" from Pernambuco whose approach owes a clear debt to the goregrind end of early 1990s extremity — their Repulsion cover signals as much. They debuted with the 2024 demo "Anatomy of the Grotesque" and followed it with the "Frenzied Necrotiscism" EP.

Necropyre is a Death/Black Metal band from Ecuador, active since 2021.
