Good discussion. I've been thinking about this myself lately. Funny thing is, I'm can't really think of a "unique", new genre/style that doesn't exist somewhere, somehow. Microtonal stuff and time signatures are taken care of in Eastern Europe and the Middle East. FWIW I'm a huge fan of Balkan folk music. There's a lot there that's been largely ignored by the western world.

Thinking we do need some new instrument types to spawn new genres. But what? And it would have to become popular enough over time too...
