Bangor’s three women city councilors called on a local concert promotion company to reassess whether its owner, who pleaded guilty to a domestic violence charge last year, should continue leading the company. “It is high time for Waterfront Concerts to think hard on whether it wants someone guilty of violence against women representing its brand and presence in this community,” Councilors Clare Davitt, Sarah Nichols and Laura Supica wrote in a statement about Waterfront Concerts owner Alex Gray. Separately, in a Bangor Daily News OpEd published Monday morning, the three vowed to improve the city’s policies on domestic violence, and acknowledged “Bangor’s own failings to address this issue.” “We hear the call for action,” they wrote.
