Les Ballets Trockadero de Monte Carlo is a troupe of male dancers who portray such legends as Jacques d’Ambrosia, Olga Supphozova and Ida Nevasayneva while hovering en pointe or executing an entrechat. For 40 years, the dancers have tickled audiences worldwide with their deft technical prowess and sly humor. This week, they arrive at George Mason University for an evening of classical ballet seasoned with graceful ornamentation, hairy chests and muscular thighs encased in leotards.
