Love this stuff, great choices; funk is my happy music so getting to discover more of it is always welcome!
My picks:
William Onyeabor is someone I discovered a few years ago through I think the Craig Charles Funk and Soul Show on Radio 6, love basically everything I've heard from him so far but my favourites are Atomic Bomb
and Good Name
Other stuff I've found through radiooooo.com (the best place I've found for finding random bits of world music.)
