Hmm, Ive heard Yoko Kannos stuff from Cowboy Bebop, and while the wild jazzy stuff was great, it was nothing like Ergo Proxy. And this is kind of the problem with soundtracks.. you tend get linked to other good soundtracks instead of similar music! I will though check out her other stuff just in case, and Raison Detre, Delerium, State of Grace, thanks!
But does anyone know what this kind of music is called (is it even called anything)? Its dark but not Dark Ambient the genre.
