Wintersun!
Or actually, anything Jari touches - Ensiferum's first two records were good too, especially "Iron" since it had Flemming with his magic on it, but Ensiferum are rather screwed since Jari left, their latest EP was a big letdown.
Back to Wintersun - I can't believe this band has such a relatively small fanbase with other
IMO semi-mediocre bands (ie GuitarWorld's-favorite-finns) being hailed as the ultimate axe wizards! Wintersun embrace such diverse elements and blend them together exceptionally well - they're like Malmsteen's "Rising force"

vs Nasum

vs Ultravox!

Or Judas' "Painkiller" vs Emperor's "In the nightside eclipse", I guess the person who invented the term "power death" got it pretty accurate, although they seem very much on the grind side of things (makes sense having Kai Hahto on drums) drumwise!
Saw them live in July, getting to see them again in 2 weeks, new record postponed to summer 2007 though!
Anyway, check 'em out if you haven't yet!
