I agree with Graveland, but...
As far as I can tell Ildjarn is now the last of the Norwegian black-metallers who hasn't forsaken quality music.
It's a bit off topic. I think it's agreeable that Ildjarn is the last of the great Norwegians, but if we expand our view beyond that country there are still a few greats out there (BEHERIT).
I think Graveland did what a lot of Eastern bands seem to do, which is rather than hit a peak of 1-3 albums and then fall dramatically down in quality an album or two later like Western bands (Emperor, Mayhem, Enslaved, Ancient, Darkthrone, Dissection, Gorgoroth... you get the picture), Darken hit a plateau that he's been traveling along ever since. It isn't a completely flat plateau, there are small ups and downs, but there hasn't been any major change in quality since Creed of Iron era Graveland, although there have been refinements to the overall formula. I think everything he has released in this decade has been at the very least good, certainly better than most of the crap out now, and I think it's a shame that people slam him for "making the same album over and over again".
I also agree that Cold Winter Blades could
be a sign of Darken moving uphill. I've enjoyed it thoroughly anyway.
