A mother of nine and supporting a family of 22, Devi was accompanied by her sons who played indigenous instruments like sarangi and dhol on stage.
Singing from under a veil, Devi says she does not even think about "leaving behind her career in music, and even wishes to sing for Bollywood some day."
"I can't think about anything but music. I have been singing from a very early age and I want to continue this until I die. I have been getting offers from Mumbai and I have accepted all. I definitely want to try my luck there," she told PTI.
"After me I don't think there is any female from my family to continue with the tradition. My sons are well versed in this gharana and they will continue with the legacy. But none of my daughter-in laws or other girls have interest in this," she said.
