Black metal project from Santiago, Chile, whose name combines the Greek roots for "crowd" and "aversion" as a statement against collective conformity. The duo of P.B. and K. have released three records — Vendémiaire (2021), Thermidor (2022), and ...In Terrorem (2023) — crafting philosophically charged black metal shaped by Nietzschean and counter-Enlightenment themes.

Ocutos emerged from Itabaiana with their 2021 debut demo Cult of the Witch, a four-track slab of raw black metal steeped in witchcraft and Satanic imagery. The recording leans into primitive production, letting the hostility of tracks like "Goat and the Moon" carry the weight over any sonic polish.

Odalheim play old-school black metal rooted in misanthropy, anti-Christianity, and the raw elemental force of nature, drawing a clear line from the Norwegian second wave. The band — built around Disintegratör, Nekromisantrop, Paimon, and Shadow — laid down their foundational sound across the 2014 demo When the Sun Has Died and the 2015 EP Praise the True Black Flame, both marked by cold riffing and an uncompromising underground aesthetic.

Odisseia dos Loucos deal in nihilistic black metal drenched in chaos, existential despair, and occult philosophy. Their debut album "O Princípio de Todos os Males," released through Death Voice Records in July 2020, pairs suffocating atmosphere with sharply conceptual lyrics, followed by the single "Metafísica do Caos" in 2021.

Emerging from the ashes of 1990s act Lethal Curse, Of the Archaengel blended gothic atmosphere with black and death metal on their sprawling conceptual album "The Extraphysicallia" (2010), a nearly 70-minute work inspired by spiritualist literature and mastered at Sweden's Cutting Room. The album featured guest vocals from Sakis Tolis of Rotting Christ, underscoring the band's ambitions well beyond the local underground.

Widely regarded as one of the first unblack metal acts in South America, Offertorium channeled corpsepaint and second-wave black metal ferocity into explicitly Christian devotional territory. Their foundational release "The Unblack Metal From Light" (1997) — featuring vocalist and bassist Fabio Carvalho, keyboardist Eduardo Borges, and drummer Alexandre "Matan" — stands as a curiosity of the era where extreme aesthetics and faith collided head-on.

Old Coffin Spirit deal in the slowest and most suffocating end of funeral doom, lacing it with black metal atmospherics to produce a sound steeped in death, darkness, and drifting spirits. Their 2015 debut, Out of the Dark...Into the Light, lays out seven tracks of cavernous, crawling misery, with song titles like "Ancient Soul" and "Nocturnal Fog" telegraphing exactly the mood they're after.

Old Throne is the one-man black metal vehicle of Fernando Count Old, a project he has driven since 2007 through a series of demos, EPs, and full-lengths steeped in anti-religious contempt and raw, uncompromising misanthropy. The 2013 album O Novo Mundo Pagão stands as a centrepiece of his catalogue, released through both the Japanese label Weird Truth Productions and domestic outlets.

Oldlands is a one-man black metal project helmed entirely by Vox Morbidus, drawing deeply on the raw, stripped-down aesthetics of 1980s and 1990s European black metal. After releasing the full-length Source of Eternal Darkness in 2019, the project matured with Oldmaster in 2023, a record structured like a vinyl side A/B split that pairs guttural and high-pitched vocals with keyboards and acoustic passages.
