Do any of today's black musicians play acoustic blues/roots music?

I'm talking about the music of Reverend Gary Davis, Etta Baker, Mississippi John Hurt and so many other greats. The only one I can come up with is Taj Mahal but what about the younger musicians of today? If you do a search on Youtube for the music of these great acoustic fingerstyle blues guitar players, it seems that the only people playing it and keeping it alive today are middle-aged white guys. What a shame that such a rich legacy of roots music has devolved into the "music" of Fitty Cent and P. Diddy. This isn't intended to be racist in any way, but I find it odd, that's all. What happened?
