Aridonia formed in San Salvador de Jujuy in Argentina's extreme northwest, with a lineup of Fernando Echenique on guitar and vocals, Benjamin Yecora on guitar, Tomas Longombardo on bass, and Matias Paiva on drums. The band released their debut EP, "EP1", in 2017, followed by their self-titled full-length in 2020, a seven-track record praised for bridging stoner metal, doom, and progressive rock influences. Comparisons to Tool, Kyuss, and Baroness have been noted by reviewers, reflecting the band's blend of heavy riffing and atmospheric song structures.

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.

As Darkness Fell is a melodic black/doom metal band from Buenos Aires that has been active since 2000, releasing the album Below the Fog in 2015 on Misanthropic Spirit Records. The record was driven by Hernan Figueredo on guitars, bass, and keyboards alongside vocalist Matias Herrera, crafting a cold, melancholic sound rooted in the Northern European black metal tradition.

Asilo was a Buenos Aires sludge, drone, and doom metal collective that built a catalog of slow, crushing releases across the 2010s, including the split with Neh Czneg (2013), Comunión (2014), and Desintegración (2019). Their approach leaned toward extended, corrosive compositions that placed them firmly within the heavier end of Argentina's underground doom scene.

Astral Drowning is a post-black and doom metal project from Mendoza, Argentina, self-described as "melancholic doom black metal from the South," that began with the demo Ocaso in 2013. Their 2022 album Traditional Music from Rooms Underwater, composed over nearly a decade, incorporates melodica, flute, percussion, and field recordings alongside conventional metal instrumentation to create a deeply atmospheric sound.

Aurora Ortus is a black/doom metal duo from São Paulo, Brazil composed of Victor Alves (guitar, drums, bass, vocals) and Dhiego Joly Botogoske (vocals), whose name translates roughly as "dawn's ascension" — a metaphor for hope emerging from depression. Since forming in 2019, they have built a prolific discography including "Drought," "Sunless Life," "Ostara," and "Against Ourselves," exploring themes of depression, mortality, and nature through slow, suffocating riffs and bleak atmospheres.

Baphomaster were a sludge/doom metal band from Rio de Janeiro whose sound drew on leviathan-weight riffs and desperate, abrasive vocals. Their 2015 demo — recorded live in rehearsal with a single microphone at Estúdio Fórum — introduced tracks like "Swamp of Sorrow" and "The Abyss," capturing a raw, suffocating atmosphere. They followed that with the album "Bong Or Die" in 2018 before splitting up, leaving behind a short but genuinely heavy catalog.

Bitterdusk were born in Santiago in 1995 and have built a slow-burning catalog that blends melancholic doom metal with progressive and NWOBHM influences, all sung entirely in Spanish. Their discography spans five albums from the debut "Pantheon" (1997) through "Guardián del Valle" (2024), the latter released on a 300-copy vinyl pressing by Czech label Doomentia Records and recorded at AudioCustom Studios in Santiago.

Black Nóia is a Stoner/Doom Metal band from Assis, São Paulo, Brazil, formed in 2017. The band blends fuzz-soaked, bass-driven stoner rock with heavy psych and elements of Brazilian rhythms such as samba de terreiro, creating a dense and culturally distinct sound. Their single “O Baque,” released after a four-year hiatus, was described by Doomed and Stoned as an intense journey through slow-driven stoner rock and heavy psych.
