Ovvercross is a heavy metal trio built around the guitar and vocals of Bruno Oliveira, whose muscular riff-driven attack sits somewhere between classic NWOBHM and the harder-edged German heavy metal tradition. Their 2021 debut full-length Stuttgart, 1943 — preceded by the EP So Survive — is a concept record centered on the true story of a nine-year-old boy sheltering from an Allied air raid over Stuttgart, turning historical trauma into anthemic, propulsive metal.

Oxida was a short-lived speed metal outfit from Buenos Aires that emerged in 2023 and dissolved not long after, leaving behind one of the more fleeting entries in Argentina's crowded underground metal registry. The band operated squarely in the tradition of old-school speed metal — the genre Argentina helped define in the 1980s through foundational acts like V8 and early Horcas — reaching back to the era when the boundaries between NWOBHM-inspired heavy metal and the proto-thrash aggression of Motorhead-worshipping bands had yet to fully crystallize. Buenos Aires has always harbored pockets of musicians committed to this unfashionably raw style, and Oxida planted their flag firmly in that territory. Their existence was brief enough that their catalog and full lineup details remain sparse in the public record, but their registration on Encyclopaedia Metallum confirms their presence in the capital's underground scene, where speed metal never truly went out of favor. Like many underground Argentine bands of their vintage, they likely played the circuit of small venues and metal fests that form the backbone of BA's non-commercial metal ecosystem — spaces where fidelity to genre tradition matters more than trends.

Pachamama is a heavy and speed metal band from Venado Tuerto, a mid-sized city in the southern Santa Fe province that sits at the intersection of Argentina's agricultural heartland and its underappreciated provincial metal scene. Named after the Andean earth goddess central to indigenous cosmology across South America, the band brings a sense of regional identity to their music — speed metal rooted in the classic Argentine tradition, where the influence of V8's foundational 'Luchando Por el Metal' (1981) still casts a long shadow over anyone picking up a guitar in the country. Venado Tuerto itself has a small but persistent metal community, with connections to the broader Santa Fe scene centered in Rosario, and labels like Herrecords operating out of the city to support heavy, thrash, black, and death metal releases across the region. Pachamama formed in 2017 and align with the resurgence of classic heavy metal values that has characterized much of Argentina's underground in the 2010s and 2020s — a reaction against the dominance of extreme metal subgenres and a return to the primal energy of speed and traditional heavy metal. Their speed metal approach favors tightly wound riffs, aggressive tempos, and the kind of visceral forward momentum that distinguishes the style from its more polished power metal cousin. As a band from Argentina's interior, they carry the DIY ethos common to provincial metal acts who build their following show by show across the country's vast distances.

Formed in Londrina around 2019–2020, Payout play speed metal with a raw punk-metal crossover energy drawing heavily from Motörhead, Venom, and Tank. Their 2020 debut demo "First Demonstration" introduced the trio's dystopian lyrical bent and a stripped-back, loud-and-fast approach that keeps the spirit of the original speed metal wave intact.
