Right well I don't know how to add videos from YouTube on here.

Korpiklaani, Agalloch, Turisas, Tyr are some personal favourites. I highly advise anyone trying to get into Folk Metal to listen to "Wooden Pints" by Korpiklaani and "Eric The Red" by Tyr. Both great songs. It took me awhile to start appreciating Folk but now I can't imagine not hearing it.
