Cocktails at the castle is a lovely affair, with drinks, art activities, and live music outside on the gorgeous museum grounds and inside the historic Turnblad mansion. For this installment, three local female singers—the melancholic Half Tramp, punk-fueled Monica LaPlante, and soul-bearing Aby Wolf—will provide tunes, along with a set by DJ duo Pink Rink. Pop-up performances include musical storytelling from Parker Genné and O’Shea Irish Dance. Throughout the evening, you can also watch rune carving and ale bowl turning demonstrations, meet some falcons from the Raptor Center, and visit the fabulous “The Vikings Begin” exhibit.
