Query: Complete surprise!

Finnish musicians who play death metal-polka and sing about trolls...sound like a recipe for disaster? Hell yes!But nope, Finntroll are actually one of the best Finnish bands out there. This album is surprisingly good and is quite refreshing. Finntroll prove you can have fun and parody yourself while actually being extremely talented, original musicians.Highly recommended for fans of extreme metal who don't take themselves too seriously.
