The acclaimed songwriter Dar Williams is never content simply to sing. Her visit to Midcoast and DownEast Maine later this month will center on a July 18 evening performance at the 877-seat 1932 Criterion Theatre in Bar Harbor. But Williams is also holding two of the “Town Talks” she’s been hosting across the country since she wrote a book about lessons in community-building gleaned in hundreds of towns she’s visited as a touring musician since the 1990s.

On Saturday the 18th at 1 p.m., she’ll appear at Hidden Barn Books in Bar Harbor to lead a conversation with local leaders and innovators fostering community resilience and thriving: Johannah Blackman of A Climate to Thrive, the Bar Harbor Story blogger and author Carrie Jones, Puranjot Kaur, a founder of Open Table MDI and John Zavodny of Maine Seacoast Mission. The journalist and songwriter Andy Revkin will facilitate.
