Formed by guitarist/vocalist Wallas Ribeiro, bassist Murilo da Silva, and drummer Gustavo Silveira, Monolito blends groove-heavy riffing with progressive structures and hard rock roots. Their 2023 album Voice of Rage, produced by Gustavo Vasquez at RockLab studio, showcases a denser and darker direction across eleven tracks while retaining the melodic sensibility that defines the band.

A project embedded in the Brazilian depressive black metal underground, Monophobia released the single "Recomeço Sem Início" on PutreRecords and the full-length Gloom in early 2018 — the latter issued as a strictly limited digipak of fifteen copies via Silentium in Foresta Records. The music draws on raw, atmosphere-heavy DSBM traditions and has appeared on national scene compilations such as Coletânea de DSBM Nacional.

Monster Coyote were a power trio who built a following in the South American stoner/sludge underground with their debut album The Howling (2012) and the follow-up Neckbreaker (2015), the latter earning positive notices beyond the region. Active until around 2018, the band performed at major Brazilian festivals including Festival DoSol and toured across South America before splitting up.

Monster Mash channel the early German speed/thrash scene — citing Vectom, early Blind Guardian, and Iron Angel as touchstones — with high-energy performances anchored by the versatile vocalist Lion. The band surfaced with the demo He Gambled with Satan and Lost, a three-song statement that mixes traditional and extreme thrash with tight cohesion.

Monstrath play old-school death metal with a heavy debt to Obituary and the brutal American 80s tradition, built on thick riffs and guttural delivery. The band signed to Swedish label Downfall Records and released the single "Child of God" in 2017, followed by the full-length The World Serves to Evil in 2018.

Montanha began their career rooted in classic heavy metal and hard rock before gradually shifting toward fuzzier, psychedelic stoner rock territory. The band introduced themselves with a self-titled EP in 2013 and later developed their heavier, riff-driven sound across subsequent releases including the full-length Alvorada.

Monte Cerrado launched with a self-titled two-track EP in March 2022, featuring the songs "Lose our Humanity" and "Fake" — an immediate showcase of their melodic power metal approach with an emphasis on strong hooks and soaring arrangements. The debut release landed on Spotify, Deezer, and Bandcamp simultaneously, signaling the band's intent to reach a wide audience from the outset.

An entirely instrumental trio of guitarist Paulo Tefili, bassist Cainã Almeida, and drummer Roger Benevenutti, Monte Resina move freely between stoner rock, shoegaze, sludge, and post-hardcore without ever settling into a single lane. Their album Aluado Bulimor (2018), recorded at Calamar Sounds in Florianópolis, was followed by the more melodically adventurous Nem Era (2025), cementing the band's reputation for textured, riff-forward instrumental writing.

Montosse was a depressive black metal duo — instrumentalist Astratta and vocalist Érdos — whose music drew heavily from H.P. Lovecraft's mythos, with the band's very name referencing a demon from The Evil Dead. Their 2019 release Pois os Mortos Viajam Depressa... showcased bleak, introspective songwriting that found a home on multiple Brazilian DSBM compilations before the project dissolved.
