There’s a review over at Metal Sucks that describes Kvelertak quite accurately:
Kvelertak‘s self-titled debut is easy listening. I don’t mean it sounds like Lionel Richie or anything – I mean it’s easy to listen to. It’s like punk-metal’s answer to a beach book – it’s just good, fun entertainment that doesn’t require too much effort or thought. Of course, there’s cotton candy and there’s gourmet candy, and Kvelertak are definitely Godiva. It’s not pop and there’s no reason to feel guilty for liking it, but it’s still bound to put you in a pretty good mood.
