Founded by Gustavo Campos and Dudu Del Bem, Menacer plays heavy metal informed by thrash, progressive rock, and classical music, resulting in a technically energetic sound built around direct, listener-focused riffs. The band debuted with the EP Rise Up The Menace in 2006, went on hiatus, and returned in 2012 with vocalist John Rodrigues adopting a heavier edge while preserving the original character of the project.

Metakiase is a two-piece heavy and stoner rock outfit from Pucón in Chile's Araucanía region, formed by drummer Tomás Trucco and guitarist/vocalist Vipe Schindler.

Mono Histeria is a Curitiba outfit blending progressive, doom, and stoner metal into a dense, riff-driven sound. The band released "Volume 1" in 2022 and has tracks such as "Instinto" and "Primata" available on streaming platforms, pointing toward a sound influenced by the heavier end of the psychedelic and doom rock spectrum.

Montanha began their career rooted in classic heavy metal and hard rock before gradually shifting toward fuzzier, psychedelic stoner rock territory.
