Not long ago, Rhiannon Giddens knew every Black string musician. The dedicated few were largely collaborators and colleagues, many of whom met a generation ago at the landmark Black Banjo Gathering in Boone, N.C.

Giddens, the folk musician and recipient of all the accolades (Grammys, a Pulitzer, a MacArthur), no longer knows everyone who followed her path. That expansion, she figured, was reason to celebrate.

She did so the last weekend of April at her inaugural Biscuits & Banjos Festival in Durham, N.C., a jamboree featuring twangy banjos, groovy basses, clickety bones and, yes, the devouring of many flaky, buttery biscuits.

The festival culminated in a reunion by the Carolina Chocolate Drops, the Black string band led by Giddens, Dom Flemons and Justin Robinson. The group met at the Boone gathering, taking apprenticeship under the old-time fiddle player Joe Thompson.

The Grammy-winning band resuscitated styles like Piedmont string music, presenting them to a broader audience.
