Inside Cirque Du Soleil’s trademark blue-and-yellow big top, a stream of dusty golden light fills the tent, like so many metallic birds flitting above our heads. It seems the perfect setting for this Quebec-based nouveau cirque’s foray into the Victorian age, in a production engagingly titled Kurios: Cabinet of Curiosities. Written and directed by Michel Laprise, the show on Randall’s Island retrofits modernity with a captivating, old-age charm. The effect is transportive; the assorted delights of fishlike contortionists, aerialists and a hugely entertaining live band, prove just enough to take the audience on a trip well worth remembering.
