Sir — M Balamuralikrishna was a music genius who enriched our lives with his immortal songs. He popularised Carnatic music so much so that it is no more alien to the hoi polloi. It is a tribute to his greatness, as a man and a musician, that his renditions of ragas appealed even to the uninitiated lay people. An incomparable vocalist, his numbers have become inseparable part of the finer side of our lives.
