It shows a great progression from their previous stuff at least. From going on what I heard of the new one, Remission > Leviathan > Blood Mountain, albeit each successive release has improved greatly on some aspects of their style while at the same time equally veering away in others which I enjoyed.
Which brings them to where they are now, and it's evolved in each direction in such a way there's too strong of a dichotomy between what I love how they've improved and what I can't stand some styles they've adopted, so .....................
In summation,
a)good for them, it sounds great
b)no thanks I'll pass
