Sorry guys, but this is NOT a bad news for me.
Immortal WERE one of the best black metal bands with albums like "Pure Holocaust" or "Battles..".
But the last releases were very disappointing to me, and, above all, were not black metal. They were a sort of slow thrash with horrible voice.
And, to all who have never seen Immortal on stage, don't worry: they were absolutely not black metal: no speed, no harsh vocals, no old songs played.
Immortal splitted? Oh, well, twas better if they splitted after "At the heart of winter".
IMHO, of course.
