Jeez, my head hurts. If it helps, I recently gt Hades' "The Dawn of the Dying Sun" and quite liked it. Very much black metal with Bathory Viking elements thrown in the mix. So, chances are I will probably like some Windir.
Mithotyn wasn't that good to my ears. Don't know, the vocals didn't do it for me. Einherjer didn't interest me much, but when I heard them I wasn't into viking metal as much as today. THyrfing's "Urkraft" was pretty darn nifty, but didn't like the first two as much.
Viking bands I do enjoy: Bathory, Falkenbach, Graveland, Himinbjorg, Hades, and Moonsorrow. That's pretty much it, so another quality Viking band would do me well. I have decided I will buy some Windir. The End has all 4 for $13 each, so when some money gets into my hands, I'll start from the beginning. Thanks, guys.
