With their newest album, Nattesferd – which they’ll present to the Hungarian headbangers on June 23 -, Norwegian metal band Kvelertak found the unlikely meeting spot between black metal blast beats and the anthemic power of Van Halen and Judas Priest.

Did their songwriting methods change with it? And what kind of memories do they have from their previous Hungarian concerts? Singer Erlend Hjelvik answered our questions.
