Except tango

The dancing sequence is taken from Tango, an acclaimed film by Carlos Saura (1996).
This film is the ultimate tango film.
At the same time, tango is imaginatively used to narrate the story of Argentina and its past.
Everything is subject to change in Argentina, except tango.
At least, this is what is believed in Argentina.
The past, to quote Borges, is indescructible; sooner or later everything returns, and one of the things that comes back is the effort to destroy the past.
In Argentina, collective memory dances.
