I'll give it a few more listens, but so far I'm finding Vespertine to be kinda boring except for the two songs I knew already. Some of the tracks sound like Björk might have been shacking up with Arvo Pärt--ethereal chords floating aimlessly in sonic space--although the squiggly little rhythmic doodads and histrionic vocals add some variety.

Someone needs to make an internet personality quiz titled "What chord are you?" Mine would have a fair amount of complexity and dissonance, but in a muted, laid-back way--perhaps something like a major 7th flat 5th.
