Kvelertak won a Spellemann Award (the Norwegian equivalent of a Grammy) in the Metal category this past weekend, and performed on the televised awards ceremony. They dressed up for the occasion, wearing some slick suits—frontman Erlend Hjelvik even kept his shirt on!—and were joined onstage by two popular Norwegian musicians, Morten Abel and Thomas Dybdahl. The performance of the song "Evig Vandrar" also featured a five-piece drum group wearing owl masks. Watch it now above!
