Beautiful singing, but i think without understanding what is being chanted a lot of the value of the art is lost. I have made several attempts at learning Sanskrit before, but progress has been slow, particularly since my memory isn't what it used to be (not sure if its because of age or stress).
My favored "Indian" music remains Hindustani music. I say Indian in quotation marks since this music appears to have been greatly influenced by Persian music, hence i suppose why so many musicians in this tradition appear to have Muslim names. The degree of sophistication and complexity of this music is astounding, but one thing that i find particularly fascinating is the how the structure of the improvisation follows the same cyclical pattern which according to the Hindu tradition is essentially an unfolding of the universe out of an overarching principle witch in itself is beyond both space and time and which represents the "matrix" of this emanation, itself containing an infinite number of possibilities that are then actualized in the relative realm, that where physical reality is situated. And as this unfolding of possibilities moves forward in time, manifestation begins to brake down as those possibilities grow more and more distant from the original source, hence, the theory of the four ages, each punctuating a new degree of separation between relative reality and its transcendent source, until this distance grows so extreme that relative reality begins to tear itself apart at an increasingly accelerated rate (since time becomes faster and faster as it moves away from its origin in eternity) during the so called "Kali" Yuga (the iron age according to the Greek tradition).
And we can see this at work in the music itself, where the possibilities inherent in the raga are slowly unfolded in a series of extremely complex variations which become more and more undisciplined until towards the end the music reaches its own Kali Yuga, where the pace of the music becomes so frenetic that the entire structure of the improvisation basically falls apart: https://www.youtube.com/v/_CtXORtvvYM
