This is an All India Radio Concert of over an hour by my grandfather the maestro Padma Bhushan Dr.S.Balachander. This special concert has just the melodic structure of a 'thanam' for the whole of the hour that he has played, but covering a wide variety of ragas. Observe the method and patters he used to change from one raga to another. Also, can you guess the number of ragas he has played in the hour and the names of these?
