"Bon," is, at least in the context of Tibet, an ancient religious practice that is said to extend its history to well before the existence of Buddhism (17,000 years ago), but is now considered one of the two main types of Tibetan buddhism today.

I believe the music speaks for itself, but it just goes to show how history and religion can lead you to some pretty interesting music.
