so you are searching for Viking Metal and thats really my genre! I know a lot more bands perhaps I will post them some day.
I dont want to open up a new thread for this, I just want to get rid of this list here. I made this years ago for another forum. It isnt only a listing of some Viking/Folk Metal Bands - these are bands I really was listening for a bunch of time, so they are all "good". So these are not all bands I ever listened to, there are enough bands just making crap in this genre
