Páramo Bonzai is a stoner/doom/fuzz rock quartet from Río Grande, Tierra del Fuego, formed in November 2018. The lineup consists of Enzo Cabezón on vocals, Rodrigo Luna on guitar, Andrés "Primo" Osvaldo on bass, and Joaquin "Pogo" Páramos on drums. They have released three records: the debut full-length Canis Majoris (2019), the follow-up EP Kwanyip (2022), and El Rey Del Abismo (2024).

A solo project built around bass-driven doom and black metal, Paranoid Existence orbits themes of Greek mythology and occultism through sparse, heavy arrangements. The project released a split with Parasito on Murdered Records (2018) before issuing the full-length Drakaina (2023) via Kvlt und Kaos, a six-track record centered on serpent mythology.

Parasitic Carnivorous is a brutal death metal/slam band from Maracay, Aragua, Venezuela, formed in 2014. Their 2016 EP "Maracay Pampero" established their sound, rooted in the city that shares its name with the release, and the band has continued with an updated lineup since 2023.

Parkcrest were a thrash metal band from the Santiago area who formed in 2011 and split up in 2023, recording their material at Lion's Roar Studio in Peñaflor. They released two full-lengths: Hallucinative Minds in 2017 and ...And That Blue Will Turn to Red in 2019, both praised for capturing an authentic 1980s thrash aesthetic without simply recycling riffs.

A pandemic-born project rooted between Natal and Recife, Paroxysm channels existential dread and societal collapse through slow-grinding death-doom compositions built by guitarist and bassist Flávio "Horroroso" França alongside vocalist Rogério Mendes and drummer Flávio Neves. Their debut full-length Faith Swallower, recorded at Black Hole Studio in Natal between 2021 and 2023 and released in January 2024, delivers six tracks of dense, suffocating extremity that treat the project's very name — the peak exacerbation of symptoms — as both aesthetic and philosophy.

Parte de Nada is a psychedelic stoner/doom metal band from Córdoba, Argentina, built around the duo of Moco Piovano (guitars, bass, vocals) and Luca Frizza (drums). Their nine-track debut album Atacan Los Monstruos was released on March 14, 2023, recorded at Gran Rosa studio and a mobile studio between 2020 and 2021, with Frizza handling mixing and mastering.

Parth Gallen was a power and speed metal band from Natal active from 2001 to 2005, drawing on fantasy worlds drawn from video games, anime, and epic fiction — references to universes like World of Warcraft and Castlevania ran through their early material. In 2024 the surviving members issued Burning Swans, a collection built from tapes recorded at a 2017 reunion session featuring vocalist Davison Pegado, guitarists Christophe Freire and Roberto Phrankson, drummer T-Rash, and bassist André Rocha.

Assembled from veterans of other extreme music acts in Euclides da Cunha, Parthak built their sound around intricate melodic arrangements grafted onto a death metal foundation — early material leaned toward progressive complexity before the band settled into more streamlined melodic death territory. Their 2008 album Red Sorrow, featuring vocalist Humberto Amorim, guitarist Ítalo Rocha, bassist Júnior Moreira, and drummer Neilton Filho, remains their best-documented statement.

Essentially a one-man grindcore machine, PartyGrind is the solo project of Igor Goularth, who handles all vocals, guitars, bass, and programming out of his Dead Icon Productions studio in Rio de Janeiro. Since launching in 2019 Goularth has released a relentless stream of politically charged short-form brutality — including the early 2020 release COVID-19 — with lyrics in Portuguese that dissect Brazilian social and political dysfunction through blasts of sub-two-minute savagery.
