Many years ago I became fascinated with the work of Bela Bartok and Zoltan Kodaly. They were folklorists who transcribed music in order to preserve it. They even made a few wax recordings when the technology became available. Also, they arranged the folk tunes for a "classical" medium. My favorite example is the Romanian folk dances Bartok arranged for piano (and has been arranged for many other settings).
Well, since then I've been searching for someone to take that approach to other regions of the world besides Eastern Europe. It turns out it has been done in India. Behold; India's Bartok:
Or maybe it is the Indian Kodaly?
