The Quebec-based entertainment behemoth Cirque du Soleil may be renowned for its non-traditional take on the idea of a circus, yet its latest show to hit the Hub, Corteo, centers around that age-old three-ring staple—the clown. In fact, an array of colorful clown characters inhabit Corteo, an alternately whimsical and melancholy tale centered around Mauro the Dreamer Clown, whose fantasies unfold before the eyes of the audience when he imagines his own funeral. Inhabited by angels, acrobats, jugglers and more, the heavenly world of Corteo comes to life at Boston University’s Agganis Arena June 19–30.
