Pesten is a black metal band from Buenos Aires, Argentina, signed to End of Humanity Records. The band contributed two tracks — "Hunter's Moon" and "Those Who Dwell In the Deep Forest" — to the compilation "Hammer of the Austral Will Vol. I" released by Ansuz Records in 2016.

Thrash and death metal band active from 2007 until their split in 2016, recorded under the Terranis Productions label and built their sound around themes of war, death, and apocalyptic destruction. Releases including "Hellish Warfare" and "Corrosive Warfare" placed them within the harder-hitting end of the Brazilian thrash underground.

Primitive black/death metal trio featuring Terrörator, Sodomköllic, and Blassphemer, rooted in blasphemous war metal and occult imagery in the tradition of the South American underground. Their 2020 demo "Sempiternal Martyrdoom" — a ten-track assault of 30 minutes released on Nuclear Winter Records — established them as a ferocious presence in the region's extreme metal circuit.

A raw black metal outfit rooted in occultism and nihilism, Pestis announced themselves with a limited-edition cassette demo in early 2023, pressed to only 64 copies. Their approach draws on the bleak, misanthropic tradition of the genre without concession to accessibility.

Pesto coined the term "culinary grindcore" for their particular strain of brutal death metal and grindcore, built around grotesque gastronomic and cannibal lyrical themes. The trio of Diego Firmo, Diego Andrade, and Marcio Barbosa debuted with an EP that included a music video for the track "Cutting Corpse," establishing a darkly comedic identity within extreme metal.

Pestífera is an Argentine old-school death metal project led by Alejandro Sabransky, also known for his work in 1917 and Bokrug. The band released the EP "Crónica Macabra" in 2020 on Total Noise Records, featuring guest appearances from members of Pogrom, Pandemia, Inhumation, and Bloodfiend.

Pethallian is the working name adopted by the Tatuí-based heavy metal project that has also operated as Pettalom, with both identities sharing the same membership and Bandcamp page. Under this banner the group released the album The Absinthe of the Apocalypse in 2012 and Ancient Bloody Europe in 2013, delivering a dark and melodic brand of traditional metal.

Petiot deals in filthy, no-frills goregrind with clear debts to Regurgitate, Carcass, and Flesh Grinder, building a prolific catalogue of releases including the full-length Xipophages and the collaborative split The Art of Surgery with Lipoma (2023). A further split, Morgue Escape, was released alongside Putrefacta, cementing the band's standing in the underground goregrind circuit.

Formed in the mid-1990s under the name Angels of Disease before settling into Pettalom, this long-running gothic and heavy metal act from the interior of São Paulo state issued their debut full-length The Wine of the Night in 2000 and returned decades later with Sanctify My Fog in 2018. Their sound blends moody gothic atmospherics with traditional heavy metal structures, drawing on a lineage that stretches back to early Paradise Lost and Type O Negative.
