I disagree, this is possible in a milonga if it’s not too crowded. It would not be appropriate in the environment of the first video pianista posted, but the second video I think it would be fine.This is not standard social dance suitable for milonga. Is clearly visible that they need 4 times more square feets then other couples and their performance is recorded. It is social dance like SHOW. Especially high boleos and ganchos performed there are banned on most of milongas.
Two previous videos were for me example of quite EMPTY dancefloor, so enough space for more intensive dance. I agree that they dance looked like buch of pensioners. On other hand, such dance style is very usefull for crowded milongas and even it looks small, it is almost impossible for begginers to dance in such compact form.
It looks like it was an impromptu recording when someone noticed they were dancing and just decided to record, hence it only captured a bit less than half the song, they may not have even known they were being recorded.
High boleos and ganchos are fine in the nyc milongas as long as they’re safe, i.e there’s space and you’re mindful of other couples, I don’t see why not. It’s only when people begin performing stage moves in a milonga here, would that be heavily frowned upon.
