On second listen, what stands out for me is the surround imaging and the different instrument placement compared with other mixes. First: you've got bass guitar everywhere, even in the center speaker. The mix is also very rear heavy, not only because some of the bass lines are in the backs, because also you've got some drums and not only percussion. You'd better have full range rear speakers for this beast.
At times, more than discrete, I would define this mix as enveloping. But don't get me wrong, it is discrete, but sometimes there's a very clear phantom image of some instruments between fronts and rears (acoustic guitars in YAM for example).
Regarding mastering, I've begun to find moments of brightness that I don't like (echoing vocals in the rears in ANM part 1 and 2, for example).
Anyway, this second listen is being the "cerebral" one and at lower volume than it should be.
More impressions about the mix tomorrow!
