Tango is a music form and also a dance form. In this highly enjoyable evening the entertainment consisted of a concert of tango numbers performed, and most of them written, by members of Tango Siempre, punctuated by some superb tango dancing from a group who performed with a riveting intensity.

While the dancers are clearly Latin in looks and temperament, the musicians are English, but have wholly immersed themselves in the fiery rhythms of tango music. All five are highly talented players: Ros Stephen - violin; Peter Rosser - accordion; Jonathan Taylor - piano; Richard Pryce - bass, and John Blease on drums. Taylor's playing in particular is quite exceptional, and he also takes the credit for composing much of the music, while three of the numbers were written by Stephen. The sound this group produces is completely authentic, atmospheric, and played with great skill, so much so that I have added one of their CDs to my already extensive collection of tango music.

To this already intoxicating mix is added the passion and glamour of the four dancers, who look as though they have just arrived from a nightclub in Argentina. They are an interestingly assorted foursome. Myriam Ojeda-Patino, who is also the choreographer, is the softer, more restrained of the two women, Kicca Tommasi the more spectacular. I have never before seen a dancer fix her partner with a continuous look of such passionate intensity, and there probably wasn't a man in the audience who would not have liked to be on the receiving end of it! Her partner, Julio Mendez, the smaller of the two men, dances with a seductive fluidity, while Guillermo Torrens - taller and more arrogant - is elegance itself.

You actually need two sets of eyes to watch tango dancing, as the intricate, interlocked footwork alone is worth concentrating on, while at the same time the dancing itself - in part a battle for supremacy, in part a willing abandonment to seduction, is totally fascinating.
