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 Friday July 17th at 7 p.m., at the Unitarian Universalist Church of Belfast, Williams will trade songs and stories with a selection of Maine songleaders of known for their focus on music as a mending and nurturing presence in our towns: Molly Gawler, Matthew Hawkins, Doug Kolmar and Mehuman. Matt Murphy, the general manager of WERU Community Radio, will facilitate.
