Exotic vocal

Orpheus10, I am sure our brains have the capacity to handle many subjects at the same time, but let's stay with exotic singing. I saw many videos with Sussan, the longer she lived outside her place of origin the more she was losing her undeniable talent and sense of the land she came from. She maintain her voice but became trivial and uninteresting, at least to me.

I wouldn't exactly call it exotic but it is certainly unusual. Kim Waters, I think, is her name. Devotion album by Rasa. She sings Indian devotional songs. Good sound quality for a digital.

How to define exotic singing? Does the female singer have to have an exotic look like Ofra Haza? Ofra has an incredible and powerful voice, but still not sure how exotic would fit in...
There are many Arab, Persian and Indian singers that are extremely good as perhaps anywhere else...

We have a freedom of interpretation of the exotic and have no need to define it in exact terms.
I thought that Ofra was okay, but Sussan's voice is much more powerful and has a lot of depth. She might also be a little frightening.
