I am new to a genre of metal (folk metal, mostly Viking themed). Would anyone have any recommendations of bands?

Examples of this genre are Turisas and Finntroll .

So I can narrow the parameters of my question, here are the following elements that particularly appeal to me: symphonic, folk (especially the Viking theme), mixture of modern and traditional instrumentation, and drive. I am still getting used to the vocal style used in these bands, preferring a mix of the growling (whatever that style is called) and more, to me, normal vocals.

I do not know if this is an appropriate question for Fluther so shall not be surprised if this question is rejected.
