Alexander Ekman’s Midsummer Night’s Dream take its cue not from Shakespeare but from what inspired the playwright: a summer solstice infused, as folk once believed, with pagan magic and mischief. In Ekman’s native Sweden, the holiday of Midsommer is as popular as Christmas, though more fun. Decked out in their wild-flower crowns, Swedes retreat to the countryside to carouse with kin until dawn. The annual fête suits Ekman’s methods—large choral casts, fierce precision, and the absurdist manipulation of outlandish props. The 2015 ballet has proven a big hit in Sweden, and also at the Joffrey, which brings it to Berkeley for its West Coast premiere. The globally recognized 42-year-old choreographer worked closely with his regular collaborator, composer Mikael Karlsson, to fashion a score that would propel us through the episodic and surreal spectacle.
