What Ethir Anduin does is quite impressive, blending doom metal and post-rock/metal with an eerie, blackened atmosphere. Besides, he does it without vocals, which makes me even more fond of the whole. It's not that I dislike vocals but instrumental music is almost always better, in my humble opinion. It also gives the whole a less obtrusive feel, making it perfect music for everyday activities. After all, that's where you get to hear this music, I don't think this is a live act.
On the other hand, songs like 'Och Ljuset Och Mörkret' and 'Längst Ner I Träsken Av Tartar' would work well on stage, hypnotizing the audience with highly immersive music. So maybe Alexey Veselov, the musician behind this project, should find some band members and get this on the road. But, I know, that's easier said than done, unfortunately. Besides, judging from the music, Alexey is a bit of a perfectionist who will not tolerate mistakes.
The music on 'I Magen Av Svart Kaos' is indeed quite meticulously written and recorded, something that seems a bit odd in the black metal genre but gives the post-rock/metal world something extra. Therefore, I would rather categorize this in that post-scene. 'Katt Vinter' for example, is a stunning track, heavy, atmospheric and precise, most of the tracks are. So I do recommend this album, but possibly not to stubborn black metal fans (who need screaming vocals to make it through the day).
