Necrolatria deal in the slow, suffocating territory where death metal meets doom, wringing funeral weight out of every riff. Their 2020 full-length Ultimate Prevail of Darkness stands as their most substantial statement, a sprawling effort built around crushing tempos and morbid atmosphere.

Necromanicider were a death/doom metal band from Rio de Janeiro active across the 1990s and 2000s under various names, including an early incarnation as Geração Eleita before settling on the Necromanicider moniker. Unusual for the genre, they grounded their dark, plodding sound in Christian themes, positioning themselves as a counter-voice to the Satanic orthodoxy that dominated Brazilian extreme metal at the time.

Nefelio announced themselves with A Peregrination Wombwards, a 44-minute debut released in May 2022 through Those Opposed Records, earning praise for its elaborate and dense approach to atmospheric black metal. The album's seven tracks weave melodic black metal grandeur with doom-paced heaviness, placing it among the more ambitious debuts to emerge from the current Brazilian underground.

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.

Lignum Mortis is a one-man black and doom metal project from Valdivia, in southern Chile, that merges sounds drawn from death metal, black metal, and dark ambient to create densely layered sonic landscapes. The project's self-titled debut was released in 2015 as a limited CD-R run of 30 copies before being made available digitally, followed by Vacuum Inferno in 2022 and Lignum Mortis II in December 2025. All music, recording, mixing, mastering, and artwork are handled entirely by the sole member.

Noctívago is a solitary black metal project that drifts between crushing doom weight and spectral ambient drift, releasing a sequence of self-titled volumes — I through V — through the Terror Noturno label, each pressed in severely limited cassette runs. The music pulls influence from post-punk as much as orthodox black metal, weaving slow, suffocating riffs with passages that dissolve into murk and static.

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. Their debut album Parawaian Drugs was recorded at Napal Studio in La Plata between December 2016 and April 2017, engineered and mixed by Fernando M. Bozzini.
