So, we have got to sit down and talk about how subgenre crazy the extreme metal world has become. It seems like with every week that goes by another fresh batch of new “subgenres” enter the metal lexicon. You see Deafheaven can’t be filed under Black Metal because they’re really a Post Existential Crisis Alternative Shoegaze Latte outfit. Ice Nine Kills’ early stuff was metalcore, but nowadays they’ve drifted over to Slasher Showtunes. I wish good luck to whoever has to classify whatever Pyrithe’s Monuments to Impermanence (Gilead Media).
