Jazz (which I am more familiar with) is a reasonable analogy. And I agree. You should be able to capture a good studio performance just the way Ornette Coleman and Coltrane could. One thing to note is that jazz has more structure. There is improvisation around that structure. Indian classical music is structured around rhythms and scales (and Carnatic music is microtonal) so it gets pretty out there.
