They can be identified by Swedish using Ä/Ö and Norwegian using Æ/Ø, but the latter are also used by Danish, which looks almost identical to Norwegian in writing, but sounds quite different

But Swedish and Norwegian are mutually intelligible and closer to each other than certain dialects of Arabic, so it's understandably easy to confuse them

Vintersorg sings in Swedish. Except on his two proggiest albums, which are in English

For someone who apparently doesn't like guitar wankery, he's very good at it when he does it himself.

Speaking of prog, I've noticed something about Devin Townsend

Vintersorg is band of prog, but i guess he only sings in norwegian.

The thing about progressive metal is that too many bands fall into the trap of just being technical, complex, showing off, while forgetting to write actually memorable songs
