Piazzolla means Tango to most people; but that goes both ways: anyone who said tango in the last twenty years immediately evoked associations with Piazzolla. And rightly so, even though it was not ever thus. Of course the tango has a much wider historical meaning; there now exists a tango beyond Piazzolla; but if anyone was worthy to put the tango on the musical map of the world (or, more fashionably on the world music map) then it was this difficult, short-tempered, obstinate, capricious wanderer.
