Meant to Suffer were a grindcore band whose sound pulled in elements of crust punk, hardcore, and sludge alongside their blasting core. The four-piece — Al on vocals, Louie on guitar, Gus on bass and vocals, and Rod on drums — released "A Step Towards Deception" in 2012 and a self-titled record in 2015 before eventually splitting up.

Mecanica was a thrash metal band from Morón, Buenos Aires, Argentina, formed around guitarist Jorge Moreno alongside vocalist Diego Leguizamón, guitarist Nicolás D'Cristófaro, bassist Luis "Bicho" Medina, and drummer Diego Nuñez. The band recorded their debut album "Códigos de Barrio" between April and August 2018 at Kirkincho Records in Morón, releasing it through Icarus Music in 2019. The nine-track record showcases old-school Argentine thrash, closing with the signature track "Violencia Es Thrash".

A thrash metal outfit from the capital whose self-titled debut was released in 2008 through Thrash Massacre Records as a limited run of 500 copies. Their sound draws on the classic Brazilian and North American thrash traditions, delivering the kind of high-energy, riff-driven attack that the genre demands.

Mediadhor hit the ground running with two releases in quick succession: the demo "Caminho do Arrependimento" in late 2016 and the full-length "Campos Mortais" in early 2017. Their approach fuses the grinding aggression of death metal with thrash's rhythmic momentum, giving the material a relentless, forward-charging quality.

Founded by bassist Samuka as a vehicle for weaving Egyptian history and mythology into power metal, Medjay released their debut "Sandstorm" in November 2020 through Voice Music, followed by "Cleopatra VII" in 2022, produced at Shokran Studios. Their sound incorporates melodic elements drawn from Arabic musical scales alongside driving double-bass rhythms and soaring clean vocals.

Megadriver is one of the originators of the "game metal" subgenre, translating the soundtracks of classic arcade and console games — particularly the Sega Mega Drive library — into full-throttle heavy and power metal arrangements. Over nine studio albums and more than 150 arranged tracks, the project has appeared at festivals including Video Games Live and MAGFest, building a global following among metal fans with a love for retro gaming.

Named after one of the three Erinyes of Greek mythology, Megaira released their debut "Power, Lies and Death" in 2017, a concept album drawing on stories from Greek myth including the Minotaur, Icarus, and the punishing goddesses who lend the band its name. The record pairs guttural death metal vocals from Paulo Schmidt against the clean, heavy metal delivery of Annia Bertoni, layering thrash aggression with melodic power metal hooks and black metal atmosphere.

A death-grind project driven largely by Billy Grind, who handles all instruments and vocals, Megalodon released a self-titled EP in 2018 followed by "Sozinho Contra Todos" in 2022. The project pulls from industrial and electro-grindcore textures while retaining the blasting, short-format brutality expected from the genre.

Formed in Taquara in 1993, Megalon built their sound around the savage intersection of death and thrash metal, channeling science fiction themes through a battery of demos — "Hands of God" (1998) and "Gattaca" (2000) — that drew coverage in national outlets like Rock Brigade magazine. The band was also a driving organizational force behind the local Thrash Attack festival and is documented in the regional rock history documentary "As Pedras do Rio Ligeiro."
