If it's Argentina it must be tango

The Tango!  Sexy, sleazy, with a graceful purity.  We succumbed to tourist fever and attended a tango show.  Near midnight we walked down a mostly deserted street until we came an even more deserted alley with a bored looking guard at the entrance.  He waved us down the corridor to a doorway with a small ticket booth.  Then down several flights of marble steps to a subterranean theater done up in bordello red velvet and gilt with small supper club tables and a fairly large stage.  The audience was mostly gringos, included a few tables of loutish Americans.  Before the show the staff pushed drink,s and photos with the tango dancers on the audience.  We resisted.  The show itself was interesting, the dancers lithe and athletic.  The costumes were one step away from tacky but they looked good on the stage.  The music, supplied by a band made up of a violin, a viola, a bass, drums, two accordian-like instruments and a piano, was surprisingly good and played a number of Piazzola tangos that were wonderful.  We wandered home late in a light rain.
