It has a unique way of adding subtle layers of sound on top of each other to a dramatic wall of sound. Track 3, for example, notice that it begins with a repetitive "rocking" riff (sorry that description sucks, but couldn't think of anything else), after a few seconds, blastbeats come in, a few seconds later, more subtle guitar phrases come in, then the screaming, then as the song continues to progress, it transitions to a sort of ambient guitar-driven section which ends with a wonderful lead... all this happening in a very dramatic way (at least to these ears). On repeated listens, you may notice sounds/changes in the songs that you didn't before, and I think that is precisely what makes "Hvis..." intriguing (along with the atmospehere). I will agree that this album is pretty damn inaccessible, especially if you compare it to previous efforts.
