Saddened to hear about the demise of Shri. (Padma Bhushan) Nookala China Sathya Narayana. He passed away yesterday (11th July, 2013) at the age of 90. May his soul be rest in peace. I was not lucky enough to meet him in person but heard a lot about him and that he was another Guru in Carnatic Classical Music.
