josepp,

don't know where you live, but I live in the North Carolina Piedmont. Lots of good things happening with Blues here among the old, the young, and the in-between, and with people of different races.

With nothing to back me up, I venture to opine that there are, in the USA, at least as many young, African-American musicians playing old time or traditional blues in the style of old-time or traditional blues as there are young, WASP musicians playing or singing traditional Child ballads in the style of traditional British Isles singers and musicians.

I think you are making an erroneous assumption that those who do not play traditional music, regardless of traditional genre, do not know, understand or value the roots and influences of the music they play.

This is a folk music site. Almost by definition, those of us who are drawn here have a strong affinity for the older forms of whatever music we like. We are focused on the roots more than the branches. Keep in mind that without the leafy and diverse branches, the roots die.

I suggest, respectfully, that you examine your assumptions.
