I really like the new one, but it seems a little watered down when put side by side w/ Archaic Course. Of course, I think The Archaic Course is also one of the best metal releases ever, so.......
Ultimately, the Archaic Course. It used to be Olden Domain or Quintessence before, but the third is the deepest, I feel. But a shame, they haven't released an album that I'd be 100% satisfied with - I hope the future will bring it !
