The tango originated in Buenos Aires, in what was (and still is) the rough-and-tumble neighborhood of La Boca. Unlike the blues in my native Chicago, which has atrophied into an Epcot presentation for tourists, the tango is still very much alive in Argentina. A common site are pass-the-hat performances like the one pictured here, where a young couple and a few musicians perform for passers-by, then literally pass the hat around periodically for tips. Of course, there are dance halls where one may try the dance oneself, but beware: the dance, as well as the attendant etiquette, is taken seriously. My dancing skills being as they are, I opted to enjoy this presentation from behind the safety of my camera.
