Amita Dutt is the only dancing legend I have seen performing in flesh. In one word she is awesome! She used to go to Burdwan every year, and performed in Krishnasayar Park on Vasantotsav (Spring Festival), I watched her perform only once, could not manage another watch but she is simply mind-blowing.
I personally think that Kathak is one of the toughest Indian dances when it comes to impressing the viewers. Because it gives a lot of importance to footwork, like tap dancing. The other dance forms of India are a lot more colourful!
Anyways I was mesmerized by her performance!
