The more I listen to Belus, the more obvious its quality is to me, which makes me all the more glad that I didn't hasten to a conclusion on it like so many others have literally while they were listening to the leak for the first time. It is, like Engram, and thankfully so I might add, a disappointment to all of those who were hoping for a Filosofem II or any of his other albums, though honestly, sans the lack of keyboards, the sound of each album is still represented here in some form or another. After getting over a few initial shocks to the system (like jumping into a freezing lake), namely the admittedly lackluster intro, the clearer and louder production, the vocal differences, and some new musical ideas, I've warmed up to the entire thing pretty quickly. That's not to say it's perfect by any means, however, though none of his works are. The aforementioned effete hammer, the inconsistency in songwriting style that is prevalent in most of his albums, the fairly static drumming, and the slightly elongated outro bring the work down somewhat, though they're all fairly dismissible.
Musically, though varied in style, the quality is pretty consistent throughout, highlights arguably being Belus' Død, Glemsevens Elv, and Keliohesten, at least for the time being. While Sverddans sounds a bit out of place, the song itself is composed very well, and the primitivism of the style (most likely arbitrarily) echoes the accompanying lyrics. It is interestingly the peak of the album in terms of tempo, serving as the climax, with the rest of the album trodding down to a restful denouement with the return of the summer sun/Belus, an interesting feature that I hope others note.
I'm also quite pleased with the way that the album is fleshed out conceptually, intertwining the Baldur myth with speculative deduction as to the myths origins in primitive sorcery. Varg himself provides much of the necessary reading material to fall deeply within this world. One of his stated goals was the desire for the listener to "get to know Belus" and to pursue that which the Belus myth entails, and I think that the album accomplishes that for those who bother to visit his webpage and read the proper corresponding translation, of which there are now ample. I have to admit that the album reignited my interest in mythology, and I found myself pulling out my old books on the Norse myths and rereading to story of Baldur. It really is a fascinating story in and of itself, and to understand how it may relate to how it relates to a more primitive time before the myth existed and how it became such a crucial element of pagan iconography just makes it even more rewarding. For anybody finding themselves going deeper and deeper into Belus, I would recommend sitting down and reading the lyrics, reading the corresponding articles that Varg has written, and reading up on the Baldur myth itself.
