Just gave a couple of listens to the albums. So far my ranking is as follows:
Dark Matters (sans narration)
Sky Blue
Dark Matters (with narration)
I'm really digging both albums. Sky Blue might be a little safe but I think it's still very good. Universal Flame, Midnight Sun, Sky Blue, and Silent Militia are all excellent. The rest? Well, I need to listen some more.
Dark Matters has lots of awesome moments, but man the narration is waaaaaay too ubiquitous. Unlike Z1, it interrupts the music way too often and it's just kind of annoying and it's just not funny. The narration-less version is so much better, almost like a different album. War Princess, Deathray, March of the Poozers, and Ziltoid Goes Home are my favorites. Unfortunately, Earth is really repetitive. It might be my least favorite on the two albums.
Overall, I'm very much enjoying this and I was really worried that the typical Devy-hype machine might ruin it for me, but thankfully not!
