The music is Gamelan from Indonesia and Bali and has intentionally out of tune (but to an intentioanl pitch) instruments to make a shimmering effect. It's quite fascinating. (also a pain to make on a digital software) They also have something called a kotekan where two seperate people play 2 seperate rythyms using only certain pitches each but when they combine together it sounds like an extremely fast rythym and the certain notes played by each person also kind of sounds like a melody.
