Pankar are a stoner/sludge metal band from Viña del Mar, Valparaíso, Chile, formed in 2014 and active as an independent act. Their lyrical themes draw on Mapuche philosophy and the cultural resistance of indigenous peoples, setting them apart from more conventional stoner rock subject matter.

Pannaural is a Buenos Aires-based project blending sludge metal, hardcore, grindcore, and math metal into a dense, eclectic sound. Their 2017 debut album Monocroma, composed and recorded at home between January and October 2017 and handled entirely by Mace Mazek, drew comparisons to Cult of Luna filtered through a grindcore lens.

Pantano are a stoner metal band from Valparaíso, Chile, operating as an independent act without label backing. The band's thematic focus spans personal struggles and everyday life in the port city, delivered through the heavy, fuzz-saturated guitar work characteristic of the regional stoner rock underground.

A trio of A. Stresser (guitars/synths), B. Silvério (drums), and F. Gusso (bass/vocals), Pantanum deal in fuzzed-out, psychedelic stoner doom built on heavy improvisation and thick riffage. Their catalog spans from the live-recorded Volume I (2015) through the garage-toned Purple Blaze (2017) and the full-lengths Geographic Animals (2019) and Innerspirit (2020).

Panteon are a melodic death/black metal band from San Salvador de Jujuy in northwestern Argentina, one of the few metal acts operating in that region. Metal Archives documents two albums under their name — a self-titled release and Septum — and the band has been active across multiple periods since the late 1990s, signed at various points to Total Desaster Productions.

Pantáculo Místico draws on the mournful, mid-paced doom of early My Dying Bride, weaving slow guitar dirges against delicate piano to create a sound steeped in occultism, hermeticism, and pagan mysticism — all delivered entirely in Portuguese. Their 1999 demo "Magnitude Oculta" established the template, revisited and expanded on the 2014 EP "Velado por Entidades" after a long dormancy.

Old-school death metal outfit drawing from the grime of Autopsy, the riff vocabulary of Death, and the brutality of Obituary, Papa Necrose deal in themes of religious hypocrisy, human contradiction, and corporeal decay. Their output includes the split Culto a Morte (2016), the album Open Infected Body (2021), and Anthropomorphy Execution (2026), released through Awakening Records.

Active since the early 2000s, Paradise in Flames meld symphonic black and death metal with Brazilian folk elements, framing their work around explicitly philosophical and anti-religious concepts they call "extreme philosophical symphonic protester metal." Their seventh album Blindness (2024) is a concept record exploring religion as psychological illness, featuring classical arrangements and the folk-inflected single "Black Wings."

Paradoxo carry on the northeast Brazilian tradition of raw, street-level crossover thrash, delivering hoarse vocals over fizzing drums and fast, dirt-coated guitar riffs that reach back to the sleazy underground of the 1980s. Their Sociedade EP (2018) established their sound with tracks like "Invasão" and "Massa de Manobra," packing nineteen minutes of manic thrash urgency.
