I haven't heard anything, but any word on what language(s) he will sing in for this album? German or Norwegian seem more appropriate than English for this album, and based on the cohesive nature of the album it would make sense to sing it all in one language.
I had the privilege of hearing the entire album on Saturday.
It's brilliant. Completely and utterly Burzum. Has more in common with Hvis... than anything else (although there are elements from both Det Som and Filosofem) and the production is immense. The intro involves some metallic clanging similar to the parts on Filosofem, but it is very short, and then the lesson in real black metal begins...
If people thought the Beherit comeback was good........
EDIT: I should have said has more in common with Hvis... and Jesus' Tod from Filosofem.
