"Modi is an iconic leader in whom I believe a lot. Today I am very proud to be an Indian. It was a very emotional moment for me," the noted singer, who performed with her violin maestro husband L Subramaniam and son, told PTI.
Krishnamurthy performed the 'Vaishnava Jan To', which is one of the most popular Hindu bhajans written in Gujarati language in the 15th century by poet Narsinh Mehta.
The bhajan was among Mahatma Gandhi's daily prayers.
Krishnamurty also performed the famous "I love my India" song evoking patriotic fervour among the 20,000-odd India-Americans present at the packed Madison Square Garden where Modi delivered an over an-hour-long speech.
