In need of the name of a rapper

I've been trying to discover the name of a rapper whose music I had heard in the 90's, to no avail. I have practically no info to go on, not even a lyric or song title, but he's got a very unique voice, and sounds almost Jamaican. He got some decent radio time if I remember, so he's not super-obscure. It's not Busta Rhymes. Any ideas?
