I saw The Matrix trilogy again recently and thought the score was really fantastic! I have earlier thought the same about this particular score and how underated it is. I thought it really got into the skin of the film and provided an excellent score......
Its hardly ever talked about.....for some reason....Don Davis is using some great orchestration/writing (Nobody else has been credited with orchestration on IMDB) and avant garde techniques there....
The blend of electronic music with the orchestra is also really great....great mix on the final matrix soundtrack too....
