I think reaching the African American audience is pretty much a dream-the African Americans who enjoy Elvis today are a small group.
I have tried in other forums to point out to young African Americans that Elvis was not a racist, did not steal his music, and that he was hugely talented-they have none of it.
The ones I debated just do not believe facts or seem to listen to reason.
If you truely believe that a big promotion on the few blues tracks Elvis cut will change their opinion-I am sorry IMO you are mistaken.
Elvis recorded a little of everything so even though he started as a Rock artist from about 1963 on he was a middle of the road artist who did a little of everything in his style. This was not someone marketing Elvis-it was who he was by his own choice of material and approach to recording-can not change that.
