When I heard that Amon Tobin was responsible for the soundtrack to the upcoming Tom Clancy's Splinter Cell 3: Chaos Theory, I made an immediate purchase of the CD. I'm glad to discover that it was not unwarranted enthusiasm. It's a good CD; it's still very much in the unique Amon Tobin style, but it's darker and a little more muted than his usual stuff. ("A little more muted" can be interpreted as "pretty insane" versus the "completely insane" that you might apply to his other music.) I'm kind of surprised at how much attention it has received; it was even reviewed on IGN's PC games site. All I'll say is that if you're a fan of Tobin's thick, hyperactive, super-electronic style, you should pick up Chaos Theory as well.
[Update] I do have one complaint about the CD; it seems like it's more repetitive than Tobin's previous albums. This makes sense; a soundtrack isn't supposed to drown out the movie or game. But, I do really enjoy the wacky unpredictability and occasional lack of coherence that I'm used to from the guy.
