Honestly, this album is just bad. His drawn out vocal style makes it seem like there's no defining melody. It's a shame because the first Zookeeper EP was incredible, one of my favorite recordings of all time. I don't know why they bothered recording "Two Part Invention" again because the vocals are god-awful this time around, it's like the demo for the original recording.
Definitely check out the first EP if you're a fan of Mineral and you haven't already, you won't be disappointed at all.
