Firt impression when Lachryma Christi heard the first songs of Faen i Helvete was: very good.
It is indeed a very good and aggressive album, very melodic, being similar to other stuff such as Mayhem on the heaviest and fastest bits, and Shinning on the doomish parts. This is not a bad point though, it is actually very nice.
Kapitel II: Faen I Helvete brings us seven tracks and so many emotions, so many introspective moments, such a good journey, it is impossible to not like it. It has really good quality regarding music and also regarding production. It is an album that you will want to hear over and over again. Really full of pleasant melodies, riffs, rhythms, voices. By the way, it includes present and past members of Gorgoroth, 1349, Koldbrann, Fortid and Nidingr.
So yeah, if you are a fan of bands like these, or even old Ulver and even Mayhem, you will enjoy it a lot.
So we can conclude that this is indeed a masterpiece.
