I'll be honest, I wasn't overly impressed with Phanerozoic I. It was fine, but far from Pelagial levels of awesomeness. For me Pelagial is such a standout album for them that I rate it as one of the greatest metal albums I've heard in the last 5 years. Everything else by them just comes in at joint second place. It's all solid but nothing really blows my mind.
All that being said, the 1-2 combo of Triassic/Jurassic | Cretaceous is the highlight of this new album and the greatest thing they've done outside of Pelagial (and the odd song, here or there from their other albums), for me.
