A class analysis of the broader metal genre would be really interesting and I don’t think I know enough to answer. I have some hypotheses and hot takes but nothing concrete.

I think metal in general evokes power and importance. Some have interpreted this to mean metal serves to reinforce masculine ideology and hetero norms, which may be true for certain artists. In recent decades though, metal fans have a more even gender split. One could make a contrary argument that metal serves to empower a powerless individual, whether they feel that way due to their class or personal issues like bullying or abuse.

Metal commonly includes themes of fantasy. Is this a form of escapism for an audience that doesn’t want to cope with the material world? Some subgenres focus quite heavily on worldbuilding. I notice that frequently these worlds involve overt evils to fight or evade… is that a reaction to the obscure and abstract exploitation of capitalism? Sometimes these worlds are plainly reminiscent of past times, precapitalist societies with simple social relations. Perhaps these would be the reactionary artists, the ones who want to go back instead of progress forward on a material basis.
