Regarding India and IDM ...
I think that if you look at the question in a larger context, Indian music
doesn't really pop up more often than other world music. I think that it's
especially well suited to IDM because of its complexity, both rhythmic and
harmonic, and because of that sort of ethereal feeling to it.
Tribal, on the other hand, is influenced mainly by African and Latin music.
Latin house also draws largely on Latin American music. I think that if
you look at the larger techno/house/IDM spectrum, just about every ethnic
genre that uses rhythm has been incorporated somewhere.
Is there anything that has used Japanese music? How about central
Asian/Siberian?
