I thought the freezing cold atmosphere created had kind of melted by the time of "Sons of Northern Darkness" but I still like most of their older stuff ("Pure Holocaust" and "Battles of the North" being my 2 personal favorites).
I'm definitely looking forward to the new "I" album as well which certainly sounds quite promising thus far.
Their promo pics are also pretty funny/amusing too.
Nice to see another Immortal fan here though. Do you like a lot of bm?
