I enjoyed the UK Channel 4 3-part series "The Voice" although the clips were too short compared with the "talking heads" but I gather there will be the inevitable CD tie-in issued.
However, I was interested when Mavis (?) Staples said in the last programme that Pop Staples wouldn't allow them to listen to blues or rock music, because in the black and white clip of the Staples singers that they showed he was playing the guitar in a style very much in the tradition of Fred McDowell and R.L.Burnside. Perhaps it was only the lyrics that (potentially)corrupted not the music!
