C’est le fun! Brattleboro Music Center’s Northern Roots Festival returns for its 18th year honoring cross-cultural traditions. The revelry commences on Friday with a French Canadian soirée highlighting prominent Québécois artists such as fiddler Pascal Gemme and accordionist Sabin Jacques. On Saturday, culturally curious music enthusiasts expand their repertoires with diverse workshops on topics from Balfolk dance to Irish immigration songs. The evening brings more genre-blending acts to the stage, including "Traddleboro" — the town’s annual collection of noteworthy local talent. Finally, in keeping with the fest’s communal tone, on-tap beers fill bellies while traditional tunes fill hearts at Sunday afternoon’s jolly pub sing.
