This is superb!
The energy throughout the album is quite similar to the previews (in a word, epic), the production is of very high quality, and the tracks complement each other nicely.
My only complaint is that there is a tension that pervades the album - even within most of the low intensity tracks - and I think a track or three to "remind me to breathe" would round everything out nicely.
This is a tiny nitpick in an otherwise amazing album. Very well done!
