The Montreal-based contemporary circus troupe Les 7 Doigts de la Main present Sequence 8, a new production that explores some of the towering themes of our existence-connection, isolation, and alienation-on an intimate human scale. The troupe's charismatic young acrobats have the elegance of Cirque du Soleil aerialists and the athleticism of Olympic gymnasts, performing gravity-defying trapeze acts and explosive somersault routines, and wryly riffing on traditional circus arts like juggling and clowning.
