I've just discovered this thread and I think it's great. I'll eventually have many suggestions. The first is a group I heard a few months ago on Afropop Worldwide (alas no longer aired in DC).
Mungal Patasar & Pantar - Nirvana
Samples can be heard at
www.ecaroh.com/indian_music/mungalpatasar_nirvana.htm, which is also the only place I found to purchase it.
The band is a fusion of classical Indian, Calypso, and jazz from Trinidad and Tobago. The band leader is the former Minister of Culture.
