...the album posted in yusuke team really isn't the original soundtrack; it's an image album (Angel Sanctuary soundtruck,..yes with the "u")wich was out way before the ova; the real OST is called "Angel Sanctuary original soundtrack" and includes the op
"Messiah" and the ed "Knife of Romance"...however, i have both cds and i have to say they are really good...:)

I know
but soundtrack or image album, I think they are both good enought to be proposed here
