I think I like Viking music so much because, no surprise, DNA testing revealed I am largely of Nordic descent. So these are like my peeps LOL.
Jormangandr...the Midgard Serpent, one of the children of Loki who will play a large role in the end of the world. He circles the world holding his tail in his mouth, like the ouroboros, and when he lets go to battle Thor in the final battle, Ragnorak begins.
These guys, the Volfgang Twins, are somme of my favorites, and the cinematography in this video is stunning as well
