The black string music tradition predates the blues. It even influenced and echoes what is today commonly known as traditional folk and bluegrass.
But don't worry if you haven't heard of it. Even one of today's most popular practitioners of what you might call black bluegrass only discovered it less than a decade ago.

''It just goes to show how underground it's been,'' Giddens says. ''Now it's definitely getting a bigger profile, and that's really great.''

Genuine Negro Jig, for example, even included a dazzling cover of Blu Cantrell's bawdy 2001 hip-hop hit ''Hit 'Em Up Style (Oops!).''
