>>5981304...Space Monke Quest?
I've thought about a "Jaxtian National Anthem" before, being heavy drums and percussion meant to be intimidating like the 2008 Chinese Olympic games opening ceremonies, though more jungle beats and less of the oriental stuff. Even though a very harmonious synth sound would be something I think would fit them, given the sci-fi background of the quest, some rabid screams and monkey noises would actually fit during the more "insane" regimes.
