Not quite self-explanatory, since whats hiding behind the title has a quite clear tango-sound - at least in parts. So...?
Thats because it was not composed as a tango. It was part of a piece for a classic string quartet, and then you cant really expect the music to sound of authentic tango... But then suddenly, after inserting more of the tango-DNA with double bass and bandoneon in this Electrocutango-version, it actually sounded quite much of tango. So now the title is a bit of a contradiction. Which is fine, since the music still is taking you on a little detour around the tango.
