Very nice soundtrack, very much liked the vibe it was going for !
I can see it easily coming from an early PS2 game where devs weren't exactly sure if they wanted to use costly CD-like music and higher quality samples played and arranged by the console, so they settled for a mixture a both (along with the skybox in your nicely made video that has some visible artifacts for the looping, not sure if this one is intentional though but it has its charm).
Concerning the tracks themselves they were very well arranged and had some nice variety, I very much enjoyed the calming vibe and progression of The Three Sages, and Bacchus The Augur had a great energy with the percussions, nails the intense vibe pretty well.
Overall great soundtrack I enjoyed my time with it, great job !
