I've actually liked Hiroyuki Sawano's vocal tracks far more than his instrumental tracks in the past, and I feel the same way here. That being said, the vocal tracks here are a bit weaker than Guilty Crown's, while the instrumentals are a lot stronger, so that's evened the gap a bit.
The previews sound pretty awesome, especially Bauklotze (I suspect it's gratuitous German? But since I don't speak German the pronunciation doesn't bother me). Looks like I might be getting this soundtrack after all--the power of standalone releases + track previews

Yeah, I'm aware of this, but I don't think Yuki's Bee Train compositions were the norm for anime soundtracks. (I could be wrong though). Her music was like an active participant in the show's creation--.hack//Sign took it to the logical extreme and felt like one long, epic music video (that I still enjoyed the heck out of, I'll add).

I agree Yuki's instrumental tracks were stronger during her Bee Train days (Noir and .hack being the standouts). Her vocal tracks have remained excellent though (Sis Puella Magica anyone?)
