When, a few weeks from now in the heat of the South American summer, the lights go up in the Centro Cultural Kirchner in Buenos Aires, one of the most unique music competitions will begin: the first ever International Contest for New Tango Ensembles. Ten out of an initial fifty-five orchestras from nine different countries will enter the stage of the CCK — the biggest cultural center in Latin America — to compete as finalists in a musical genre which, until not too long ago, has been seen as a thing of the past. It will be the grand finale of a week-long gathering of tango musicians who will have participated in a study program called Tango Para Músicos.
