It was easy to find to Tango O'Nada just following the instructions on the site - you find the URL below - and it was generous too with the payment. No one at the door collecting the fees but a bowl on the bar table. When you pay your 10.000W you get a drink and I choosed to have a bottle with a cap to take with me when it was time to go home!
The crowd was young and very skilled dancing tango salon. They were musical, placing the feet exactly and not shoveling around at all. Many dancers were expressing the music in the body, dissociating beautifully, lowering and raising the body softly to the music.
Most of the leaders managed a quite dynamic dance in a space usually llocated by the crowded pista. Only one younger Asian leader and a long legged foreigner clearly needed a double space at the ronda.
There was even a very skilled female leader and you can spot her here in a white shirt, black trousers and a scarf around the neck as an alternative tie.
And here some feet!
You can even see how beautifully the outer line is formed!
