Noala carves out an extreme corner of the sludge and post-metal world by fusing the wall-of-sound density of Neurosis with industrial texture reminiscent of Nine Inch Nails at full volume, resulting in a sound that is both corrosive and hypnotic. Their 2013 debut "Humo" runs across seven tracks and an hour of material, with compositions stretching past fifteen minutes and building through alternating layers of crushing riffs, harsh vocals, and quieter atmospheric passages.

Named after the legendary ghost ship whose crew perished under mysterious circumstances, Ourang Medan channel that maritime dread into slow, crushing sludge and doom built around themes of cosmic horror and the occult.

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.

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.
