In the immigrant quarters of Buenos Aires, the tango became farewell and memory in the dreams of it's inhabitants. Music of districts of ill repute and faraway places, a love ravishes a dance step just before the moon's suicide. Tango, song of rivers. Gardel and Piazzola transformed it into a bottle launched out to sea. On it's southern-bred staff lived a melody made up of rhythm and dream. One late afternoon, it was discovered on the banks of the Saint-Lawrence River. It stayed there, pulsating from four different instruments. Like a harbour for seemingly endless voyages, "Quetango" arrives in the 21st century. A voice revealing new and unforeseen sounds and timbres. A music whose destiny is young, in which Québec City and Buenos Aires discover each other.
