Not a huge fan of this as an album, but I dig a few of the individual tracks pretty well. Second Song, Killer Crane and Caffeinated Consciousness are all pretty tight. I hate CC as the closer though, it reminds me a bit of I'm Gonna DJ closing R.E.M.'s Accelerate, and I hated that almost equally. They're both anticlimaxes, and CC is especially unacceptable because, in spite of how haphazard the whole record was, its predecessor Dear Science felt circular thanks to its excellent, thoughtful bookends. I have no idea what the hell happens at the end of this album, but it ain't a mark of great sequencing.
Also, I'm not big on the production of Nine Types of Light; it worked with danceable numbers like Golden Age and Dancing Choose, but it's pretty damn slick for such moody songs as Killer Crane and Will Do. There's not a lot of atmosphere here, certainly not to the degree of Return to Cookie Mountain, which you could cut with a knife. I love the production of that record, and it would have enhanced these songs.
Anyway, not bad, but they're capable of much, much better. The new Panda Bear and Fleet Foxes would be completely overshadowing this right now, but I'm writing an article about this album for the university paper, and I needed a couple extra listens before I could form even a tentative opinion.
Also, Keep Your Heart is being underrated right now. Good track.
