Karmapa is a great Congo Rumba artist. I have a couple of his albums/DVDs. For somw reason he has never found success as financially as Koffi or the Wenge team. One thing I have come to find out is that outside of Congo, not many Africans are into pure Rumba like Karmapa plays; it has to have a mix of strong sebene and of course prancing stage girls and boys. He needs that Europe crowd and big concerts. I have not seen a Karmapa concert though.

He has a couple clips on Youtube, I've been trying to track down his first and and recently released album with no success.
