IF I HAD my choice, I would take my flamenco in its original form as a solo performance: one dancer in competition and collaboration with one or more musicians. That kind of presentation is perhaps less theatrical – and certainly not as useful on the grand stages that flamenco commands these days – but sitting in a smoky (you can't have everything) bar in an alley in Cádiz, or even Madrid, and participating in that visceral connection between dance and music can be pure bliss. However, if flamenco has to come in the form of a grand troupe, you can't do much better than Ballet Flamenco Sara Baras. Quite simply, it's a class act. Baras is an exquisite dancer, and her sense of style – she has appeared as a fashion model – is reflected in the voluminous costumes she chooses; they are made of soft material in order, as she says, "to allow you to see the body." This program, a suite of dances dubbed Sueños, goes back to traditional flamenco, emphasizing music and dance and forgoing more recent excursions into rock, world music, and drama. But she's no reactionary. One of the program's highlights should be Baras dancing Farruca, traditionally danced by a male and with ferocious footwork.
