Exotic vocal

Yeah, Lisa Gerrard is mostly excellent, sometimes great. I just thought that everyone knew her singing and didn't mention it.
But Lhasa and Sussan are much more sensual, right? Lisa is quite cold and abstarct if you get into her voice.

Damn, that was supposed to be "abstract" but didn't come out right.

Yes that's Lisa's style more abstract than cold.

Lhasa and Sussan have got a lot of pain in them, both of similar and differend kind. You can hear it.

Same song by Lhasa that you posted, Czarivey. Slightly different take.
