One of the earliest Brazilian thrash bands, Necromancia came together in São Bernardo do Campo in the mid-1980s and spent decades honing the groove-inflected thrash attack that defined their later records. Check Mate (2004), produced by Sepultura's Andreas Kisser, marked a high point in that evolution, blending the bone-dry riffing of Pantera-era groove metal with their São Paulo thrash roots, while Back from the Dead (2011) pushed the tempos back up toward their earliest material.

Necromancy from Vila Velha play a savage blend of black and death metal that leans heavily on speed and menace, releasing a steady stream of material since their 2019 debut Feathers Fall to Flames. Savage Genocide (2020) and the self-titled full-length (2022) further defined their approach — raw, uncompromising underground metal with no concessions to accessibility.

Necromanicider were a death/doom metal band from Rio de Janeiro active across the 1990s and 2000s under various names, including an early incarnation as Geração Eleita before settling on the Necromanicider moniker. Unusual for the genre, they grounded their dark, plodding sound in Christian themes, positioning themselves as a counter-voice to the Satanic orthodoxy that dominated Brazilian extreme metal at the time.

Necromansy Rites emerged from Betim in 2024 dealing in vampyric, necro-inflected raw black metal, debuting with the five-track demo Black Goddess Cadaverine released in August of that year. The demo sits firmly in the lo-fi Brazilian black metal underground tradition, all hiss, distortion, and malevolent atmosphere.

Necromante are an occult black metal outfit from the Belo Horizonte area signed to Iron Bonehead Productions, drawing on the dark ceremonial tradition that has long defined that city's underground. Their album The Primitive Conception of Evil — recorded in 2014 at Studio Attack in Belo Horizonte and released in 2020 — showcases a primitive, ritualistic attack with tracks like Fire of Death and King of Blasphemy anchoring its feral energy.

Necromatório rose directly from the ashes of Sanatório, with the same four members — Pablo on vocals, Lucas on guitar, Andrei on bass, and Marcus on drums — carrying the torch into harder territory when the previous project dissolved in 2017. Their 2018 debut, Vida Longa Aos Incrédulos, balances the boundary between thrash and death metal with five tracks of Portuguese-language lyrics attacking social and religious dogmas.

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.

Necropolis is a death metal band from Córdoba, Argentina, featuring guitarists and vocalists Guillermo Gomez and Pablo Camiletti alongside bassist Pedro Larrahona and drummer Juan Bustos. They released their debut album Incertidumbre in 1999 and followed it with a second full-length, There Is a Place, in 2007, and have continued performing in the Córdoba metal scene into the present.

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."
