The eclectic Toronto-based “guerilla-folk party-punk band,” Lemon Bucket Orkestra, leads a call to arms in the immersive and interactive Ukrainian folk-opera, Counting Sheep. Sung in traditional Ukrainian polyphony and bolstered by first-hand video footage from the streets of Kiev, the production invites audience members to dance, sing, and eat—and hurl foam bricks, dodge men with guns, witness violence, and join in the rituals of public mourning—as part of an emotionally gripping remembrance of the 2014 Maidan Revolution in Ukraine.
