Exotic vocal

Think this was asked before in the thread, but what do you guys mean by "exotic"? Does it mean not mainstream, or not common, or not white, or not western, or third-world, or "ethnic" ? Or all of the above or is it that it makes you feel that the music was otherworldly?

Not mainstream, not expected as per Western cultural standards, my guess... As when Debussy infused Eastern tunes into Western mainstream 100+ years ago. Not that easy to define nowadays that we r all mixed and racially-"corrected" but some genetic/racial knowledge tells us what that is.
like for me, Tchaikovsky's 4th under Karajan sounds "exotic": the guy never heard Russian folk tune "the birch in the meadow" so his take is beautiful but "exotic" to my ears. 

Natalie Merchant

Ofra Haza. She is my all time favorite vocalist. No one comes close to her. She has that voice that hypnotizes you.
Picking a favorite song from Ofra Haza is hard, but Jerusalem of Gold is one of my favorites.

(P.s:, someone here said that Ofra's voice was just ''okay'', if that's what you think then you need to clean your ears and listen again. You have no idea what you're talking about. Peace)

Excellent song and Ofra's voice sounds beautiful. I don't much like her singing in English, but that's how record companies make money.
