NEWTON — Before any piano keys were struck or opera arias sung at a Russian arts and culture festival Friday night, Newton Mayor Setti Warren sounded a somber note, reflecting on the Boston Marathon bombings and ensuing manhunt that ended in nearby Watertown.
“Last week was so tragic for this region, this city, this country,” Warren said. “But through that, what is so vitally important . . . is that we continue to celebrate what makes this community so strong and vibrant.”
