one could argue that metal is by ethos much closer to de facto nihilism
unrepentant longhairs making unrepentant ugly power chord noise, fuck everything
the edges always get sanded off, but at the beginning point
Blue Cheer ca. Vincebus Eruptum, Hellhammer, Slayer ca. Show No Mercy, early death metal (a young Glen Benton: "death metal is freedom"), etc
unlike punk the trap there is technical proficiency
tho as Lemmy predicted, once the punks learned to play their instruments they more or less did start playing metal, so the snake eats itself (which is fuckin' metal, bro)
