And gamelan in general is a Hindu aristocratic art form a long way removed from paganism.

I'm given to understand gamelan still has a folk life & lore of its own, as far from any orthodoxy as the Bon Shamanism that still persists in Tibetan Buddhism. The exterior influences are an essential part of the process, though it's a two way thing, as testified by Debussy's reaction to Javanese Gamelan during the 1889 Paris Universal Exposition. I've got recordings of Sumatran village ensembles mixing gamelan instruments with old military brass left behind from colonial days. In any case I was thinking of Pagan more in terms of the Exotic, which might take us from the Icelandic lithophones of Sigur Ros to something even more remote... http://www.youtube.com/watch?v=OJK2LwD_nEY
