While a partial extraction can be found here (http://forums.ffshrine.org/f72/xbla-hardfile-rips-77145/6.html#post1666500), I am curious as to whether anyone who has in their possession the actual soundtrack (http://vgmdb.net/album/25125) is willing to share it.

Seconding this. The Side Vower BGMs are fantastic.

Release date is 8 june in Amazon JP:

Seisou Kouki Strania OST (http://www.amazon.co.jp/gp/switch-language/product/B004W8PN2Q/ref=dp_change_lang?ie=UTF8&language=en_JP)

Hey man,
if you're still interested, the full strania soundtrack is now available.
Love the music btw.

It's in my HD, thanks :)
Great stuff, sounds like a x68000 shooter soundtrack on steroids.
