Aceldama is a stoner/doom duo from Quilmes, Buenos Aires, Argentina, built around guitarist and vocalist Ayatola el Infame and drummer El Musulmán. Their 2023 release "Demasiado tarde..." — recorded at El Portón studio — stretches across four sprawling tracks including the ten-minute closer "Estramonio," sitting comfortably in the heavy psychedelic and doom tradition. The album's full subtitle, referencing being "too late to think about God," signals the band's bleak, riff-driven worldview.

Acidemia is a stoner/doom trio from Lages, Santa Catarina, Brazil, formed by Henrique Soares (bass/vocals), Mateus Varela (guitar), and Thiago Granetto (drums), drawing heavily from Electric Wizard and Monolord. Their 2021 album Podridão marked a shift toward compositions entirely in Portuguese, blending sludge-inflected doom with psychedelic heaviness across seven tracks. The band has been featured on the Weedian-curated Trip to Brazil compilation, placing them among the notable voices in Brazil's growing stoner/doom underground.

Arrastado is a stoner and doom metal project from Brasília, Brazil, formed in 2018 and built around home recordings under the name that translates roughly to "dragged" in Portuguese — apt for the slow, crushing tempos the band favors. Their releases include the album Isso Também Será Esquecido (This Too Shall Be Forgotten) and Hinos do Esquecimento, both available on Bandcamp and consistent with the heavy, fuzz-driven doom aesthetic. The project's DIY approach and introspective Portuguese titles reflect the broader character of Brazil's independent stoner-doom underground.

Asterias is a stoner/sludge metal band from San Juan, Argentina, featuring Diego Oliver and Juan Montané sharing guitar and bass duties alongside Rodrigo Cardozo on guitar and Pedro Romano on drums. The quartet released Hijo de una Tormenta in 2021, a record that channels the heavy, riff-driven energy of South American stoner rock into dense, atmospheric territory.
