Nice band! I haven´t heard any real album though; just a demo record, brought to me by some musical relatives of mine (who aren´t into metal at all, actually). How known are Lumsk in the Norwegian territories?
Right now, it's a bizarre combination of Edvard Grieg's Piano Concerto in A minor and Iron Maiden's Seventh Son of a Seventh Son. Surprisingly, the two get along pretty well. Some interesting aural things can happen when one person's music bleeds into somebody else's in the office.
