This is just one of many ways Tango has been branching out and changing with the times, for the last 20 years at least.
When I first arrived in BsAs, in 2007, the whole Electro Tango movement was already close to ten years old- Narcotango, Gotan Project, and Bajofondo had all been revisiting Tango in new ways since around 2000.
Orquesta Tipica Fernandez Fierro had started a kinder, gentler reexamination of Tango in 2001- with dancing, weekly, that soon became known as "cargo pants tango", which was truly inspiring but decidedly non-traditional.
The whole idea that Tango must remain, lost in amber, EXACTLY as it was 100 years ago, was discarded by Argentines 20 years ago, and the movement had been quietly growing ever since.
There will always be a place for traditional Tango- nothing will be "lost".
But the ways it is appreciated, and the people doing it, will continue to change and grow.
Look at Daniel Melingo- famed Rock Nacional pioneer, who played with one of Charly Garcia's most famous bands, Las Ligas, in the early 80s, who led rock and electronic bands, and has played with musicians of every genre here and in europe- and who has become the Tom Waits-like musician to find himself in Tango anew- Believe me, Gardel would have totally dug this-
There is never just one way to do anything.
