One more thing before I head off for more Kimikiss - someone brought up the Pure ~ Aquaplus CDs in the Asian music thread. Arrangements are sparse and a bit muzak-y at times, but the recording quality, even listening from the streaming previews, are JAW-DROPPING good. Also a 2nd, jazz version, which I ordered on an impulse.
Plenty of classic OST renditions on Platina Jazz: Anime Standard volumes as well (Kenshin, SEED, etc). I grabbed all three volumes off a bookstore shelf for dirt-cheap prices.
Well, that's it for me. Off to Kimikiss!
