Any metal fanatic worth their salt keeps tabs on the vast and encompassing Metal Archives, a site which classifies and organizes almost all known metal bands, both active and inactive. That being said, I was surprised to find Norway’s Kvelertak hasn’t made the cut. I thought that the Scandinavian brand of headbanging hard rock these guys were playing was surely metal. Or at least they had come to fit within the parameters that I had assigned to heavy metal myself. And with a name that literally translates to “stranglehold,” wouldn’t most people categorize Kvelertak in the same way? Listen to their new album, Nattesferd, though, and it becomes clear that Kvelertak defy the very idea of categorization in favor of just playing some damn good rock ’n’ roll.
