As I'm listening some music/studying. I wanted to share the glory of Yuki Kajiura with VGC. She is the composer for the absolutely excellent Kara no Kyoukai (Garden of Sinners) movies. They're excellent, well reviewed, and generally accepted as amazing.
Anyways, here's some of her work.
From the first movie.
M12+M13
From the fifth movie. (I can't find a link to the whole thing. It's 15 minutes long and amazing.
M23
From the 6th movie.
M15+M16+M17
And Finally, I have two from the last movie.
M41+M42
and the awesome violin riff mostly used for fights.
M40
I hope someone else enjoys the music!
EDIT: Yuki Kajiura is a girl. My bad.
