I’m not sure exactly who it was that drew such rigid lines around metal. While pioneers like Sabbath and Maiden were wide open to other influences, somewhere along the lines, metal shored itself up and went to war with other music. It’s not just softer styles either—metal fans and hardcore fans often come to blows with one another. Even subgenres within metal itself have split into warring factions.
But there is a growing movement in heavy music in the last decade or so to lay down the purity tests and elitism and infuse a wider range of influences into their work. One of the most exciting acts in this realm that I’ve discovered is the Danish quintet MØL. While they might lazily be tossed under the blackgaze umbrella for lack of better categorization, there’s a lot more going on here than Alcest worship.
