We call y'all "non-tango people" - everyone who has not (yet) experienced or really even seen social Argentine tango being danced. This is one of the most accurate portrayals of the scene/s at a milonga, or social tango dance, that I have ever seen.
Although this shows only one song, we dance with the same partner for three or four songs, what we call a tanda. Everyone leaves the dance floor during the cortina, then via cabaceo/mirada, a completely non-verbal eye contact only process of invitation and acceptance, everyone mixes it up with new dance partners and the process begins anew.
Milongas occur every night of the week, in cities large and small, all over the world. Most go from 10 until 1 or 2 am, however, some last until the wee hours of the morning, or even day break.
It's a beautiful dance and art form, a UNESCO Intangible Cultural Heritage, and as I am oft to say, it's not "just" a dance.
