Jahnavi has a really amazing voice and often sings mantra and prayer. She also makes a genuine personal connection with her audience which goes far beyond and deeper than anything I have ever experienced at live performances (and I've been to literally thousands of concerts and gigs). It's not "happy clappy" and there's no pressure to join in if you don't feel like it - very easy going. Many people have had amazing experiences hearing her singing, but my advice would be to go and see her, listen with an open heart, and leave the rest to Jahnavi.
