I never thought I would say this: the best scene in Buenos Aires Tango is one with taped music. The latest show by dancer Miguel Angel Zotto has a mix of live and recorded music, dramatic scenes and simple dancing. The simplest, and loveliest, is a nostalgic scene with Zotto and his partners dancing to a series of classic, crackly recordings. This is the richest dancing of the night, showing off period style in a brilliant variety of rhythms. In the wittiest of these numbers, Zotto and his partner dance along the edge of the stage, here and there dipping a foot over the brink. It’s fast, stylish and sophisticated dancing.
