A journey to the Buenos Aires underground tango culture, where the elusive soul of tango is to be found... Even after a century of history, after enshrinement as the national music, after rampant commercialization and packaging for export, the tango still speaks to the Argentine soul. Subtango shows how tango music, dance, art and poetry are an essential part of the emotional expression of regular people, featuring the gamblers, ramblers and barroom prophets of the Buenos Aires night, playing weather-beaten accordions and singing old tangos of heartbreak and resentment.
