Your Favorite Viking/Folk Metal Band

Nice list. I've still yet to check out Skyforger, but I plan on doing so soon. Which album would you recommend?

Semigalls' Warchant which is their demo, and Kauja Pie Saules which is their debut album. Their later albums depart from the folk-tinged black metal style. Latvian Riflemen is not really a folk metal album, but rather more of a black metal/heavy metal hybrid. Swordsong is just a straight up folk album. Thunderforge is definitely folk metal, but it's more accessible than their earlier works (and therefore less interesting, as far as I'm concerned).
