Mörbidez is a one-man black thrash project that recorded its entire debut, Sob o Signo de Belial, between April and May 2020 at the creator's own Casa da Bruxa studio in Vitória. The album channels the ragged energy of first-wave black metal and South American speed metal through nine Portuguese-language tracks steeped in satanic imagery, and was released in June 2020 alongside a bonus covers EP titled Limbo.

Mørk Visdom crafts raw symphonic black metal steeped in Luciferianism and occult darkness, releasing their debut "Fenrisulfr" through Impaled Records in 2012.

A raw black metal cult drawing directly from the second wave Scandinavian tradition, Mørkalv features members with roots in other extreme underground acts including Necroholocaust and Blood Sorcery. Their 2023 debut album "An Ancient Cult to the Aesir" delivers eight tracks built on Nordic themes, cold-blooded riffs, and an organic, deliberately rudimentary production that suits the band's uncompromising aesthetic.

Founded in 2010 by bassist and vocalist Marcel Ianuck, N.W.77 (Nuclear Weapon 77) play old-school crossover that sits at the intersection of hardcore punk and thrash metal, citing Suicidal Tendencies, S.O.D., Municipal Waste, and Ratos de Porão as key touchstones. The band has been prolific on wax, with releases including the albums Youth Explosion and Nuclear Awake, and the 2025 EP Touching the Terror appearing on CD, 7" vinyl, and cassette through multiple international labels.

Their 2013 debut album "Press Start to Try Again" features fast, aggressive thrash driven by socially conscious lyrics focused on global crisis and individual agency. The lineup of Luis Orozco on vocals, Yonht Figueroa on guitars, Giuliano Lossio on bass, and Félix Castañeda on drums draws influence from classic thrash acts such as Metallica, Megadeth, and Slayer.

Nadarkhani are a Christian black metal project from Santa Bárbara d'Oeste whose 2021 album Divine Transcendence Supremacy anchors explicitly theological lyrics to a raw, lo-fi black metal framework. The project features Abisai Darkaliel on guitar and bass alongside Melancton Samengaleff on vocals, operating within the unblack metal tradition that runs against the grain of the genre's typical anti-religious posture.
