Replacing a composer at the last minute can be a difficult thing to master. The music has to be written and recorded in a certain amount of time and fast. That is exactly what you get for the score to The Bourne Identity and the music really reflects that. John Powell did do a good job considering the ample time he had to write the score so late in the game, replacing Carter Burwell. With that in mind, the music is full of electronics, synthesizers, drum loops, and a small orchestra. "Main Titles" is a good track containing the main theme, which is a repeated sixteenth note pattern for strings. This theme gets played again in later tracks, such as "Bourne Gets Well", "Jason's Theme", and "The Bourne Identity." "Treadstone Assassins" contains all out electronics and drum loops with occasional strings thrown in. "Escape from Embassy" and "The Apartment" contain some exciting action material with lots of pulse pumping electronics, orchestra, and heavy percussion. The rest of the tracks are mainly filler music with your usual blend of electronics, synth pads, and a small orchestra. This soundtrack is actually good, considering the little time Powell had to write the music. Had he of started much earlier, the music would have been much better. Still worth checking out though.
