Apparently, Ustad tari khan is a tabla player from Pakistan. Might be singing 'shaukia', much like Rais khan, Sultan Khan etc.(I have to put that gazal by Rais Khan someday on this blog). I dont know many artists across the border anyway. I was searching for 'famed' hansadhwani rendition by Ustad Amir khan and landed on this thanks to utube recommendation engine.
The opening is just heavenly, the first 40 seconds are very very sweet but suddenly, it becomes a usual song though still bearable. But the opening is magical!
