One trend in contemporary circus, says Wall, involves full shows based on a single technique, such as juggling or trapeze. The team behind Compagnie XY specializes in hand-to-hand acrobatics. "They climb on each other and vault each other and throw each other around," says Wall. "It's very charming and wistful. It's gorgeous." Based in Lillie, France, Compagnie XY tours around the the world and is performing its show "Le Grand C" as part of the historic New Victory Theater's Ricochet family series in New York, April 18th–8th.
