I wasn't interested in that topic so much to read the whole article, but even in the first sentences it suffers the typical blindness of accepting only a small part of music as cultural valubale.
But what seems true is that india managed it to establish its traditional music in a level that western feuilletonists can accept it as something playing in the same league.
Which is, in my opinion, not something coming from inside the music, but from the cultural environment, in the rituals, where and how it is celebrated.
