It just doesn't sound like Burzum anymore. That's not me whining about wanting another HLTO or anything, but it is a comment on the fact that I could be listening to anyone on that sample track. Belus was passable but didn't blow my mind, I gave it the benefit of the doubt given the pressure he was under. But this and Fallen I choose to see as coming from a completely different entity to the original Burzum.
Also, the more I listen to his new vocal style, both clean and distorted, I get increasingly annoyed by it, and that was one of the most glaring flaws in the re-recordings. I just couldn't listen to Spell of Destruction without the original maniacal screech.
