So I'm an all around Metal head... I listen to everything from Norwegian Black Metal to Death Metal to Progressive Metal, but have recently really gotten into Celtic Folk Metal. It isn't too often that you hear bagpipes along with heavy metal guitar or electrified mandolin lol.
Here is a band called Eluveitie, they are a Swiss Folk Metal band
