The version you've got there is a bit of a Faux Pas amongst old Dimmu fans. Thats from one of thier earlier albums which was alot grittier, alot rawer in terms of production. Thats what black metal was back then, but as it evolved, new bands started to deviate from the norm and began to favor a much clearer, crisper environment. Dimmu were one of these bands who started to leave the older style behind and embrace the more lavishly produced style, enter the Faux Pas. Thats a re-recording of the old album, in the more modern style, and some of the more die hard fans boycott the shit out of it.

Nothing wrong with good 3rd wave Black metal though, so if you're enjoying that you should check out the "In Defiance of Existence" album by Old Mans Child. OMC are the sideproject of Dimmu's guitarist Galder, and that album is probably thier best. You'd also likely enjoy Graveworms "Engraved In Black" album, particularly the track Legions Unleashed.
