Just an initial impression, but I get the feeling this album might be slightly better balanced than Dum Spiro Spero, at least for my taste. Don't get me wrong, Dum Spiro Spero is one of the heaviest albums around, and I love every minute of it. To me that album easily belongs in the 9-9.5 out of 10 range, near perfect overall. If there is one MINOR complaint I have, and it's very minor and doesn't really drag down the album anything for me, but it would be that the album is very heavy-centric, and despite some calmer songs, it goes more into the extreme territory than Uroboros did. Arche (at least after one listen) felt a bit more balanced, and one of their most atmospheric sounding albums. Less heavy, some more clean stuff but overall a nice mix. When they go heavy, they really go heavy and you get blown away.
So while it is too early to judge this album, and how it will stack up to Uroboros and Dum Spiro Spero, I will say that I loved the balance of the album. Heavy, soft, and some really nice new additions to the sound. Also possibly their best artwork in a while, and I love the title of the album. So yeah, time (and more listens) will tell how it stacks up quality-wise, but I do love the dynamics on it. It's like a slightly lighter Uroboros/Dum Spiro Spero hybrid, and I agree with PolarizeMe that it feels like some of the earlier albums had a touch of influence on this one.
