Némesis is a thrash metal band from Concepción, Chile, formed in 1998 with influences drawn from old-school thrash and death metal acts including Slayer, Kreator, and Malevolent Creation. The band released a self-titled album in January 2016, marking their continued presence in the Chilean thrash underground after more than two decades of activity.

Nîn Morn is a doom/death metal band from Santa Cruz de la Sierra, Bolivia, formed in 2011 and signed to No Wasted Records. The band progressed from early EPs — Funeral (2012) and The Black Box (2015) — to their debut full-length Victus Paradisum in 2021, building a sound anchored in themes of death, despair, misanthropy, and nature. Their 2019 EP Valle de la muerte and 2023 single Lament continue to refine their dense, grief-laden approach to the genre.

Nöldr is the solo black metal and dungeon synth project of Lord Deathlaff, whose 2021 debut Misanthropic Forest established the project's tone: raw tremolo-driven riffs shadowed by a melodic melancholy, closing into dark ambient territory. Subsequent releases including the Dynasty ov the Darkened Evocations EP and Profane Eternity deepen a cosmology drawn from Tolkien, Norse myth, and the bleak aesthetics of second-wave black metal.

Nādha released their self-titled debut in 2022, a ten-track record that weaves progressive and death metal into a bilingual framework of philosophical and introspective themes, drawing on Sanskrit imagery in the band's name. The Rio quintet — featuring guitarists Juan Carlos and Rafael Rassan alongside drummer Jean Falcão — balances technical density with melody, moving between Portuguese and English across tracks like "Anāhata" and "Ephemeral Being".

A two-person project built around Pedro Caldas handling all instrumentation and Joaquim Ghirotti on vocals, O Anjo Exterminador channeled industrial noise, grindcore, death metal, and experimental electronics into a single claustrophobic whole. Their sole full-length, Tetragrammaton (2005), runs 71 minutes and pairs occult lyrical conceits with artwork by sci-fi and horror illustrator Edgar Franco, closing with a cover of Swedish hardcore legends Anti-Cimex.

Rooted in the northeastern underground scene, O Cão deliver a direct and uncompromising brand of crossover that draws on the combined experience of guitarist and vocalist Hugo Medeiros, bassist and vocalist Eddie Cheever, and drummer Átila Mesquita. The trio has built up a catalog across three releases — Demonstrando, Devorados pelo Cão, and Original Espanta Crente Style — each leaning hard into the abrasive, no-frills energy that defined 1980s crossover thrash.

Assembled during the pandemic in late 2021, O Espírito Profano wrote entirely in Portuguese and drew their themes from death, misanthropy, and spiritual suffering. Their short-lived run produced a self-titled release and a live EP recorded at the UFCAT university festival in Catalão, blending black, death, and doom metal into a dense and despairing sound before splitting up.

Operating under the pseudonym Lord Caronte, this Rio de Janeiro one-man project explored pagan metal built around themes of fantasy and mythology. The band left behind a demo, Forgotten Tunes, and contributed the track "Nameless Fairy Maiden" to the Stimmen des Ideals compilation (2007) before eventually dissolving.

Oath of Persistence work in the space where death and thrash collide, building their catalog around Lovecraftian and dystopian themes that run through releases including the demo Deadly Tentacles of Summoning, the album The Myths, and the 2023 EP Arrival. The three-track Arrival tightens their attack into focused bursts, with tracks like "Fear of the Unknown" and "Queen of the Swarm" showcasing the band's appetite for cosmic dread wrapped in grinding riff work.
