This song is simply amazing. It starts out slow like Schala's theme, but then the fast paced drum loop kicks in at about 0:16 to give the song some life. The change of the drum loop at 0:33 is somewhat sudden and could be done better, but it doesn't take away from the song. When Schala's theme comes in at 0:45, it manages to be the main focus of the song without overpowering the other instruments. The pauses/breaks/whatever in the drum loop are very well timed and make the song what it is. The beginning part of Schala's theme at 2:35 is quiet, but noticable. I actually didn't hear it until the 3rd or 4th time I listened to the song.
Overall, this song took a huge creative risk, and it paid off big. And for some reason, it reminds me a lot of the song at the beginning of Men In Black (which I haven't heard in years, so I have no idea what it sounds like any more).
