Hey while I am waiting for the complete Hell Chapter ost to become available to buy, I found that on amazon.com Japan you can listen to 45 second previews of all the songs. So I listen to them. IT WAS AMAZING! Bleach's score has become Evangelion good (also composed by Shiro Sagisu). I mean it felt very different from any score for Bleach I have heard before. I mean Hell (not meant as a pun) Shiro reused themes from the Bount arc and actually made them sound good! So I will completely forget the crap-tastic ost 2. The feeling it gave me was really undesirable. I guess the closest thing I could think of is it sounds like a mix of John Williams, Alexander Desplat, Hans Zimmer, Nicholas Hooper, Alan Menken, it really felt like (not that it didn't before) a film score. I think they used more people it the orchestra and it sounded like the recorded it in a new building, because the sound is so much richer. I believe Shiro currently lives in London, and I know he usually collaborates with the London Philharmonic Orchestra (famously for Evangelion, but more recently Bleach). I am not totally sure on this, but I think judging by the acoustics I would but my money on Air Lyndhurst Studios (where Harry Potter and the Goblet of Fire was recorded). The score was excellent, differently a buy (whenever it's available on amazon.com US). Anyway don't take my world for it listen for yourself.
Just go down near the bottom of the page under listen to samples, and click listen next to the tracks, a pop-up player will appear. Enjoy Everyone!
My favorite tracks are track 1 Incantation (Part C__Opus1), Track 2 Cometh the hour (Part A__Opus1), Track 4 Cometh the hour (Part B__Opus1), Track 6 Then We All Can Go Home (Part B__Opus3), Track 7 Lucifers Dance (Part B__Opus3), Track 18 BL06__Sakkaku, and Track 19 Monologue (I think this is the song that will play during Gin's death, it really is one of the saddest songs ever). I liked all the tracks though. I found to like a lot more tracks on this ost, than other Bleach osts in the past, where there were only 3 or 4 I really liked.
