I only like a few songs from the album. I don't like Belus as much as Burzum's older works but I'm not disappointed either. I already thought Filosofem was only half a good album, I think the Rundgang track is boring and usually skip the second half of the album. I thought it was disappointing when Varg stopped using the high shreeks, I can appreciate the songs on Filosofem but the vocals sound like Ministry. On the other hand I'm not sure how tracks like Daughters of Firmament would have sounded with traditional Varg shreeks but anyway that's just some background info why Belus doesn't disappoint me that much.
On Belus I dislike Glemselens Elv because it's just a boring sugary track. It feels like he tried to translate the same atmosphere as the softers songs on Hlidskjalf into a metal song but it completely fails imo. It's too soft and just boring, like mentioned elsewhere it's just flowery wallpaper. Sverddans is another offender, it sounds like a joke track. This is what I miss most in Belus: a sense of earnestness. Kaimadalthas' Nedstigning is amusing, it's cool hearing Varg sing in a clear voice in this song but it offers nothing of what makes the older works so great. The only tracks that save the album for me are the last two tracks (or one track and one outro, I prefer to see them both as one track) Those, for me at least, at last capture that feeling that I expect from Burzum (having felt that in all his other albums including the ambient ones) A feeling of seriousness. With Belus it feels like the epic has been replaced with pretentiousness, the fact that Varg took some older songs of lesser quality and then present Belus as a great album because of it's subject matter says enough for me. The drama with the title change said too much already.
What I'm really curious about by now is: who wants more? It should be no secret that this album is indeed just a test, a new debut if you will. If this album proves to be (or sell?) successful chances are that mister Vikernes will create more albums. Perhaps he will put more effort in those and not all is lost, or perhaps it will turn into what Darkthrone is now. Time will tell. At the moment I'm reluctant to write off Burzum completely. I just hope he quits trying to make concept albums like he did on the ambient works, it worked then but it fails on Belus and that's sad because he really seemed to want to send out a positive message with this album.
