Tango originated in Buenos Aires brothels but later evolved into a ball dance. This show is back to roots, group porn dance.

I have never seen tango this raunchy, but I am not surprised.

I am, however, familiar with the tango being danced on the streets in Buenos Aires. Each Sunday at the San Telmo market (a large street antiques fair) tango dancers entertain the tourists.

And below a show from La Ventana, one of the major tourist shows in Buenos Aires.
