People are commenting on Soundcloud that this has a great deal of King Crimson in it. I have to agree that some parts sound uncannily close to early 70s KC, but it's still Ihsahn wandering ever further into his own creative world. I personally think this guy's solo work is becoming increasingly better with each consecutive release. "Das Seelenbrechen" should be excellent at least.
