Pezadilla is a death metal and grindcore band from Medellín, Colombia, active since 2011. The band recorded a live session album in 2012 and appeared on the split "Purulenta simbiosis" in 2022, with an additional full-length "Medellin Morgue" noted in their discography. They operate as an independent unsigned act.

Phantom Menace traffic in occult-drenched speed and black metal with a vampyric edge, releasing a rapid string of singles and EPs in 2023 including All the Witches Hail, Chained in Lust, and the Night Galleries collection. Their raw, first-wave-informed attack pulls from the same vein as early Bathory and Venom with a Brazilian underground sensibility.

Phantom Star draw from the classic heavy metal tradition of Dio and Iron Maiden, blending epic riffing with progressive structures and a cosmic, horror-tinged atmosphere. The Curitiba five-piece — featuring vocalist Matheus Luciano and guitarists Lucas Licheski and Mauricio "The Fox," both veterans of speed metal outfit Hell Gun — debuted with the single "Touch of a Curse" in 2024 and followed it with "I Am the Storm" in 2025.

Phrenesy play a no-frills thrash metal rooted in the aggressive German and American traditions — think Kreator's intensity crossed with Anthrax's groove — with flashes of death metal adding extra weight to their attack. Vocalist Wendel Aires fronts the Brasília quintet, whose debut album "The Power Comes from the Beer" gave way to the harder-edged "Fears Apocalypse" in 2022, a record whose title was changed from "Beer Apocalypse" during recording as a response to the pandemic's toll on Brazil.

Phronexis is a thrash metal band from La Paz, Bolivia, originally founded in 2017 as a one-man project by Alvin Phronexis before evolving into a full band. The name is a stylized take on the ancient Greek concept of phronesis — a form of practical wisdom or mindfulness — which informs the band's introspective lyrical direction alongside themes of disease, horror, and death. Signed to The Foul Swamp Productions, they have released two full-lengths, Pestiferous (2020) and Opulence of Metal (2024), establishing themselves as a consistent force in Bolivia's thrash underground.

Regarded as one of the earliest black metal bands to emerge from Rio de Janeiro, Phuneral came together in late 1984 around guitarists Gilson Zumbi and Marcelo Tumor, with Jorge Abominável on bass, Gilson Bruxo on vocals, and Fabio Cadáver on drums. They played the local circuit — venues like Circo Voador and Crepúsculo de Cubatão — until disbanding in 1986, leaving behind only live recordings and photos rather than any studio release.

Piah Mater is the progressive death metal duo of vocalist/guitarist Luiz Felipe Netto and guitarist Igor Meira, whose dense, Opeth-influenced sound weaves dissonant extremity with extended atmospheric passages and a disregard for conventional song structures. Across three albums — "Memories of Inexistence" (2014), "The Wandering Daughter" (2018), and "Under the Shadow of a Foreign Sun" (2024, Code 666) — the duo have steadily carved out a more distinct identity, incorporating jazz-inflected saxophone work by Jørgen Munkeby on their latest record.

Picaporters is a doom and stoner rock trio from La Plata, Argentina, consisting of Juan Pablo Herrera Morales (bass/vocals), Lucas Barrue (guitar), and Juan Pablo Vázquez (drums). The band has released three albums — "Elefantes" (2013), "El Horror Oculto" (2016), and "XXIII" (2019) — all sung in Spanish and drawing heavily from 1970s doom, psychedelic, and heavy rock influences.

Piedra Cuarzo is a doom and stoner metal band from Jujuy, Argentina, formed in April 2019 from two pre-existing projects. The four-piece — Gonzalo Mariscal (bass), Nahuel Burgos (guitar), Antonio Cruz (guitar/vocals), and Marcos Rotten (drums) — released their debut EP "XUXUY" in September 2020, blending instrumental and psychedelic elements with heavy, sludge-inflected riffs.
