Napalm Death and Primitive Man

Napalm Death, formed in Meriden, England in 1981, pioneered grindcore, blending hardcore punk and death metal. Known for extreme speed, blast beats, guttural vocals, and sociopolitical lyrics, their influential albums include "Scum" and "Throes of Joy in the Jaws of Defeatism". "You Suffer" holds the Guinness World Record for shortest song. They have collaborated with artists like Melvins and are a top-selling death metal band.

Primitive Man, originating from Denver, Colorado in 2012, is an American doom, sludge, and black metal band. They are known for an intensely heavy, abrasive, and nihilistic sound, delivering crushing riffs and a suffocating atmosphere. Notable albums include "Caustic" (2017), "Immersion" (2020), and "Observance" (2025). They also collaborated with Full of Hell on "Suffocating Hallucination" (2023).
