This question already has an answer here:
I've been scouring google for over an hour, but I'm at a loss as to how to search apparently.
I'd like to know what the singing style used here is called. I've tried looking for Balkan vocal styles, eastern singing styles etc, but the closest i find is "turbo-folk" which is clearly not about the singing.
Obviously it's the "vibrato" style of his singing. I've heard it before in lots of Balkans based music (Greek, Serbian etc) but also in muslim cultures like Bosnia and further into the middle east/Turkey.
I'm curious where that style of singing comes from, what it's known as etc.
 The post mentioned in the comments does not answer the question,- the question is similar, but no answer was given to the actual name of this style. Is there none ?
