Mortífera from Campina Grande holds a notable place in Brazilian metal history as one of the country's earliest all-female death metal bands, active from the late 1980s into the early 1990s and documented on Metal Archives with a 1989 rehearsal demo. Their brief existence in the northeast underground left a mark as a rare example of women fronting the uncompromising heaviness of early death metal in Brazil.

Motra are a death metal band from Sorocaba whose lyrics dig into mental disorders, pain, and psychological collapse. Their 2025 album 'Óbice' — a ten-track statement of unrelenting brutality — earned the band international attention including coverage in Russian metal media.

Mourners Lament is a death doom band from Viña del Mar, Chile, active since 2004 and recognized as part of the Chilean doom scene alongside Uaral, Mar de Grises, and Poema Arcanus. Their catalog spans four releases — from the debut Unbroken Solemnity (2008) through We All Be Given (2017), released on Hammerheart Records, to A Grey Farewell (2024) — a nearly 65-minute album of crushing riffs, guttural vocals, and atmospheric synths.

Mufa is a São Paulo extreme metal act that draws equally from death metal brutality and hardcore aggression, keeping a stable lineup since 2011 while channeling outrage at social rot into relentlessly violent music. Their 2015 debut full-length "Brutality Show", recorded at Magma Studio, showcases their genre-defying blend with tracks like "NarcoViolence" and "Disposable Human Race".

Murder Worship plays uncompromising death metal rooted in violence, anti-Christian themes, and a relentless appetite for brutality. Their catalogue includes the 2013 debut "Hate Celebration", the 2020 EP "Bleeding the Coward", and the 2021 full-length "Doomsday", the latter reissued in 2024 with live bonus tracks from Festival Marreco.

Formed by guitarist Jazz Kaipora and vocalist Claudia Franco, Murderess weave together death, black, and doom metal with lyrics centered on female resistance and historical figures erased by official narratives — including a track dedicated to Soviet WWII sniper Lyudmila Pavlichenko. The band released the EP "Time to Kill" in 2024 and followed it with "Time to Kill: Volume II" via Electric Funeral Records, quickly earning attention beyond the Brasília underground.

A three-piece funeral doom outfit recorded at GoreZone Studios in Belém, My Funeral Dream released the EP A Beleza De Um Funeral and the album Introspectivo in early 2017, both sung in Portuguese. Their sound leans heavily on suffocating tempos and cavernous vocals, placing them firmly in the tradition of European funeral doom while maintaining a distinctly raw, underground Brazilian aesthetic.

A one-man industrial deathgrind project, MySilentGod released Mundo Herege in 2019 — an 18-track assault of mechanized brutality with anti-religious Portuguese-language lyrics spanning tracks like Jesus Ateu and Demônio. The project fuses the abrasive density of grindcore with industrial texture, occupying a confrontational niche in the broader extreme metal underground.

Formed in Salvador, Bahia, Brazil in 1989, Mystifier are one of the foundational acts of the Brazilian black metal underground. Their debut full-length Wicca (1992) and its follow-up Göetia (1993) established a ferocious and malignant sound steeped in occultism and anti-Christian themes, earning them widespread recognition in the international underground. After an eighteen-year gap between studio albums, Protogoni Mavri Magiki Dynasteia (2019) on Season of Mist marked a powerful return.
