Caralisa for title song and it is not lip synched and almost nicely reproduced

I guess almost is the key word here. In the first iteration of the pallavi, she could barely execute that Aaaaa vocalise. Her next attempts were better but still nowhere near the smoothness of the studio recording. Benefit of doubt: maybe she didn't get enough time to rehearse and/or there were problems with the equipment set up. Be that as it may, just going by this performance, NEPV launch performances seem to have been a much better advertisement of the album.
