I've tried to get into Amon Tobin's music for a long time. I've always thought that there was something inherently dull or repetitive about most of his other work, but I noticed that Chaos Theory is a lot different. It seems to have more rhythm and substance than other albums of his. I never played the original game, but still enjoyed this soundtrack, which is testament to the fact that is strong enough as a stand alone album.
There are some solid tracks, such as El Cargo and The Lighthouse which roll along in a mechanical manner and easily generate a feeling of stealth and subterfuge. I think this is probably Amon's best work.
