Metal Genocide is a Santiago-based speed metal trio drawing on the old-school ferocity of Razor and Running Wild, with members carrying backgrounds in Chilean acts Impact, Battlerage, and Steelrage. Their debut album Speed and Genocide, recorded at Fullrock Studios in Santiago, was released in 2013 through Rawforce Productions and set the template for the band's uncompromising, pro-true-metal stance.

Mortal Whisper is a heavy metal band from Santiago, Chile, formed in 2016 by vocalist/lead guitarist José Tapia alongside rhythm guitarist Cristóbal Moreno, bassist Matías Rodríguez, and drummer Francisco Cerda. Their 2016 self-titled EP, recorded and mixed by Cristian Lion at Lion's Roar Studio in Peñaflor, showcases a driving sound rooted in traditional heavy and speed metal.

Motorbastards are a Motörhead-devoted power trio from Curitiba led by bassist and vocalist Carlão Bastard, whose rumbling low-end and raspy delivery draw unmistakable parallels to Lemmy Kilmister. The band channels classic rock 'n' roll aggression through a speed metal lens, and their debut album of original material, 'Divisão Rock N Roll,' sold its entire limited pressing within a year of release.

Formed by guitarist and vocalist Jean Nightbreaker, Murdeath delivered tightly wound thrash and speed metal with a NWOBHM edge across releases like the 2014 EP "Apocalipse Sangrento" and the 2016 full-length "Sob o Signo...". The Curitiba outfit announced a hiatus in late 2022 following a final show with Skull Fist in early 2023.

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.

Mötim is a speed metal trio from Rio Grande do Norte comprising vocalist and guitarist Alexandre Almada, drummer Glenio, and bassist Gustavo. The band delivers fast, stripped-down heavy metal with an aggressive underground ethos, documented across a run of self-released recordings on Bandcamp including "Heavy Metal and Rotten Hearts" and "Genocida".
