Indoor Bluegrass Festival and Cantus Vocal Ensemble

The Champaign-Urbana Folk and Roots Festival will host its third annual Indoor Bluegrass Festival on Saturday, with four local bluegrass groups, and space for jamming. On the Thursday edition of “Live and Local,” we’ll hear one of those groups, called Black Coffee Fridays, live in our studio. And I’ll talk with Aaron Humble, one of the tenors of the Minneapolis-based men’s vocal ensemble Cantus, who will perform in Jacksonville Saturday night.
