Netuno Doom blended stoner and sludge with progressive and doom textures, threading science fiction and Lovecraftian cosmic horror through slow, heavy riffs. The Fortaleza trio of Adriano Alves, Hewerson Freitas, and Bosco Lacerda released the conceptual EP The Universe The Prison in 2018, one of the more distinctive stoner/doom efforts to emerge from the northeast Brazilian underground.

Norep Aviv is a stoner/doom metal band from La Plata, Argentina, formed in 2016 and known for blending the genre's classic heaviness with outside influences and rhythmic variety.

A trio of A. Stresser (guitars/synths), B. Silvério (drums), and F. Gusso (bass/vocals), Pantanum deal in fuzzed-out, psychedelic stoner doom built on heavy improvisation and thick riffage. Their catalog spans from the live-recorded Volume I (2015) through the garage-toned Purple Blaze (2017) and the full-lengths Geographic Animals (2019) and Innerspirit (2020).

Per Umbram are a doom metal and stoner trio from Buenos Aires whose debut album 'Obscuri,' released on April 25, 2023, arrived as one of the more fully realized first statements in Argentina's increasingly vital heavy underground. The band's Latin name translates roughly to 'through shadow' and comes from the Virgilian phrase describing those who travel dark and alone through the night — a phrase that perfectly encapsulates the album's psychedelic, hallucinatory atmosphere. The six-track record runs through thematic territory ranging from media manipulation and systemic control ('Industrial Sanity') to mythological war imagery ('Long Fangs'), psychological isolation ('Fairy Tale'), and politically charged conflict ('No Mercy'), all filtered through a genuinely heavy lens of angular sludge riffs, powerful vocals, and extended song structures that reward patient listening. One reviewer described the album as 'angular stoner goodness from Argentina' that 'may take a few listens to fully appreciate but then will fast become a favourite' — an accurate summary of music that reveals itself gradually through accumulated weight rather than immediate impact. Per Umbram describe themselves as a trio who view music as something that works through them rather than something they consciously create — 'musical artifacts' through which their vision manifests — a philosophically serious approach that sets them apart from bands treating doom and stoner metal as purely aesthetic exercises. Buenos Aires has fostered a thriving doom, sludge, and stoner scene documented in outlets like Bandcamp Daily and through local compilations like those released by the Sabbra Cadabra label, which has helped map the broader Latin American heavy underground. Per Umbram fit naturally within this community while bringing their own distinct identity shaped by Buenos Aires's urban intensity and the vast emotional landscapes that define the best heavy music from the Southern Cone.

Doom and stoner metal band formed to pay tribute to the classic heavy sounds of Pentagram, Cathedral, and Black Sabbath, releasing the debut EP "Here She Comes" in 2015 and first full-length "Bring Out Your Dead" in 2016 via Black Farm Records and Death Time Records. Their 2019 album "Faith Bathed in Blood" — which includes a Sarcófago cover — earned widespread praise from the international doom community and appeared on numerous year-end best-of lists.

Dual female-fronted stoner doom outfit distinguished by a gnarly, fried guitar tone and a rare willingness to mix Portuguese and English lyrics in equal measure. Their 2023 self-titled debut — six tracks including "Velho Jack," "Bruxas," and "Labirinto da Morte" — draws on classic stoner heaviness while maintaining a compact, focused sound that avoids the shapeless drift common to the genre.

Projeto Trator is a São Paulo duo grinding out dense, abrasive sludge and doom with dark guitars and hypnotic low-end grooves over a prolific catalog that stretches back to their 2007 debut EP.
