I'd imagine that from this point forward, the countries I pick should all be pretty much expected. The only question would be the order I choose. Well, here's the country that managed to just miss my top 5.
From the nation most synonymous with black metal, it should come as no surprise that black metal bands dominate my selections. These groups, with the sole exception of Windir, are all pillars of the Norwegian black metal scene and should be familiar to most metal fans. Of course, Windir are hardly unknowns themselves, and alongside Enslaved and Bathory are one of the names most associated with Viking metal. The trouble I have with Norway, and the reason I didn't place them higher, is that outside of their infamous black metal scene, the country's depth of contributions to metal take a much steeper dive than those of their neighbors. At least that's my opinion.
