What I unfortunately had to realize is that the sound quality is not just managed. Both on my system from CD, as well as OGG Vorbis files on my music player, the bass in my opinion, come over a little weak. The percussion sounds less like what it is, than for someone who strikes a pan with a wooden spoon. No comparison to the previous albums with the well-tuned and rich low tones (which I would be interested if only I feel so).
My conclusion: I would buy the album at any time. The music is great and is fun! Only the sound quality is lagging behind a little!
EDIT:
So I already repeatedly listening to the album intense and at rest, and I must say it is absolutely great! The quality of the Northmen's usual high level. As for the bass, I maintain, in the previous albums had a the depths of my opinion, much more violent! Since this is obviously just my subjective opinion, I correct my vote on full five stars!
