Lumsk
Lumsk, a band that describes itself as:
A seven headed “troll” that combines traditional or traditional-inspired elements from Norwegian folklore and poetry with progressive rock and metal.
Formed in 1999 In Trondheim, Norway, LUMSK set out to explore the concept of regional folk traditions, as did many European heavy metal bands towards the end of the 20th Century. So great, in fact, was that interest, and its ensuing popularity amongst fans, that, by the first decade of the new Millennium, it had burgeoned into a significant sub-genre all of its own.
