Here’s some clean and well controlled female vocals from Kyrgyzstan that I came across last winter:
Ayana Kasymova
And a duo with Ayima Ayilchieva:
Both of these are on Ayana’s EP Суротуно on Google Play, which you can’t even find unless you spell it (or her name) in Cyrillic characters. 
Speaking of language barriers.
And for those of us dealing with toasty weather these days, something nice from Mali (Africa):
Fatoumata Diawara
I recommend the whole album Fatou.
