En Sus 13 is a series of nine flamenco dances from award-winning dancer/choreographer trio Olga Pericet, Manuel Lion and Marco Flores, and their company.
Hailing from different parts of Spain and with varied flamenco backgrounds they have put together a show that clearly highlights the variety of styles and tones that exist within flamenco, to the advantage of their breathtaking skill.
This is excellent to see, as flamenco is far more complicated and diverse than simple stamping feet and clapping hands. In fact, flamenco was perhaps far too technical for its own good in this case.
Within the vast, formal chasm of the staid Town Hall an outstanding display of vastly complex choreography and dazzling technical skill was somewhat diluted.
Losing the intricacies of the movement meant that a big degree of the visual intensity was lost and it became more about the audible percussive element. And there is certainly plenty of that in this rhythmically razor-sharp showcase, not only from the dancers but the world-class musicians accompanying them - who were equal to their dancing compadres both in ability and status on the stage.
It's just a shame that the visual passion was secondary to the audible.
Interestingly, the male dancers suffered less from the drawbacks of the venue.
The stronger, more dramatic lines and spins of their unashamed masculine posturing meant that the male solos provided many of the highlights - although Olga Pericet also displayed a striking presence on stage.
All in all it was a remarkable display of skill in an atmosphere that lacked electricity. The fierce passion in flamenco can never be entirely quashed - even on a Tuesday night in a big hollow hall with an unresponsive audience - but just put that show into a crowded, noisy bar in Seville and you'd scorch the skin off the front row.
