I absolutely LOVE the Imaginarium soundtrack.
Thanks for sharing this music, I had no idea that there was still unused music out there... I bought the re-release of the OST because it had the unused music and early demos, can't see why they left this one off there.
But while on the subject, here's one of my fav tracks, "Jose Felliciano":

Ya, love this game. Tracked down a copy of the PlayStation version years ago just to have the cleaner FMV's but was pretty sad to see the game was dubbed instead of subbed... So the voices are terrible. Especially Klog. *shudder*
