The very best

That's their name, the very best. They are Radioclit, a british producer, and Esau Mwamwaya, a singer from Malawi. The music that results is amazing, a combination of reggae, island, african rythms, and electronic music. They had a free mixtape that came out in 2008, and there are a few great tracks off of that.
Cape Cod Kwassa Kwassa - The Very Best
Get It Up - The Very Best
Dinosaur on the Ark - The Very Best
Download the whole mixtape here (i would highly suggest that you do so)

Now they've got their debut album, "Warm Heart of Africa", coming out soon, and its leaked. The two songs I've listened too are amazing, with a bit more of an electronic slant than the mixtape, but still with Esau's amazing voice, and some high profile guests. I really enjoyed the mixtape a lot, but they have one-upped themselves with this new album.
Julia - The Very Best
Rain Dance (Feat. MIA) - The Very Best
(both songs removed from the internets, guess you'll have to wait till the album comes out)
