Actually it was composed by Hridaynath mangeshkar for lata ji. And Tai used to sing his compositions so maybe inspired from that

Sorry, mere paas is concert ka video nahi hai.

The Jaipur Gharana Gayaki's Vilambit Vistar is never overly slow. In Jaipur, Ati Vilambit is generally not sung and Vilambit itself is a bit faster than, say, a Kirana Vilambit. Kishoritai broke Gharana boundaries but one can never completely forget at least the positive aspects of one's upbringing. As for the contemplative mood, you are entitled to your opinion on that and I respect it. It is a subjective matter after all. But I feel she has elaborated the Raag quite leisurely. The tabla is a bit loud though but that's negligible enough.
