Wonderful review by Sarah Bardeen on Rhapsody about the San Francisco show last Saturday:

“When Spanish flamenco sensations Son de la Frontera came to San Francisco on Saturday, March 1, the hip, educated Bay Area audience thought it was ready. There’d been a stellar article about the rough rural outpost, Morón de la Frontera, where most of the band members come from and the region’s passionate, raw music. The show opened with a video clip of the band’s inspiration, guitarist Diego del Gastor, and his vocal collaborator La Fernanda de Utrera. The Bay Area Flamenco Partnership even gave not one but two introductions before the show started. But nothing could prepare the crowd for what they would experience over the next hour and a half: a live show so stunning it defied all classification.
Reviewers might be given to hyperbole when discussing Son de la Frontera, but it’s for good reason. The show opened acoustically — no mics, no instruments, just five guys in black suits and black shirts standing before a teeming, sold-out concert hall. Singer Moi de Morón, an unassuming man, opened his mouth and let out an ungodly wail — a lament so deep, so gruff, so ancient that it sent shivers through the crowd. A peppering of “ole”s burst from the flamenco aficionados in the audience, as if against their will: they sounded as if they’d been struck in the gut. When Moi was done singing, dancer Pepe Torres, whose grandfather was the noted Gypsy dancer Joselero, stepped forward and began to knock his shoes against the board below him. It was the first of many breathtaking dance (or baile) sessions — and just a taste of what was to come….
At one point, Torres took such a long baile solo that the audience broke in with rapturous applause and ovations three times before it ended. He strode off the stage, leaving the crowd in a frenzy, and the band wisely kicked into a well-mannered bulería that gave the audience a chance to cool down and collect themselves…
The show ended with a hilarious dance by Manuel Flores, whose playful moves echoed spontaneous pueblo dances done by drunk uncles, and a guest appearance by Juan del Gastor, Diego’s nephew. Again the group left their microphones behind, performing with nothing between themselves and the audience, while del Gastor sang with the drama and humor of a true veteran. When the lights went up, the crowd let out a mighty exhalation and went out, very reluctantly, into the night.”
