Vani Ramamurthi is from california(I think some where around Los angeles and orange county) . She is presently tutored by ranjani gayatri sisters. Vani's dec 2016 music academy review that came up on Feb 03rd,2017. Certainly great talent is coming from that land - the likes of sandeep narayan, ramakrishnan murthy and Aditya Prakash. Best wishes to Vani in her musical pursuit.
