Country people got some names, now. "Demetriss Tapp"...I coulda gone to high school with her (although I didn't). Never mind who my wife went to high school with in Boomer, West Virginia!
Y'all come live here for a while, in the American South, in a warm weather/agricultural climate and around people of entirely rural heritage (or what's left of it....more than you might think). Don't form assumptions based on impressions and/or limited and controlled exposures. Come see the real world of the real people.
Nothing about that record sounds "black", it couldn't be anything but a "country" record. Soulful, yes, plenty. But it's a "country" soul, and the way the "discussion" has been formed over the decades, "country" is coded as "white", and "soulful" as "black". That's bullshit, it really, really is, but there we go again with categories making it too easy to think without thinking, to feel without feeling.
Nancy Adams, however...just file that one under WRONG.
