Those of us raised in a social-dance universe where people rarely touch one other may find tango impossibly difficult — and supremely sexy. Developed in Argentina in the late 19th century, it has absorbed, and resisted, many cultural influences. At once precise and fluid, linear and curvaceous, rhythmic and melodious, the dancing of Cia Unión Tanguera, hailing from Buenos Aires and Lyon, France, emphasizes everything essential about the form, and nothing extraneous. In Nuit Blanche (“Sleepless Night”), Esteban Moreno and Claudia Codega, dance partners for more than 20 years, imagine a traditional tango club where the spectators can’t help but join the soloists. Seven dancers and four live musicians both honor and liberate the genre, taking tango to places you’d never expect to find it.
