Each week, 89.7’s Brian O’Donovan explores traditional and contemporary music from around the Celtic world, connecting emerging artists to their deep musical roots. In honor of Labor Day, A Celtic Sojourn features “Songs of Work and Workers,” a variety of songs from America’s railroads, mines, mills and labor strikes that provide the backdrop for the social history of America itself.

Listen Saturdays at 3 on GBH 89.7 or the online stream.
