Long before the dangerous social situation in which Mexico has fallen during the last three years, SERGIO ANDRADE used to write songs which dealt with social issues. But it has been during this new era in his career that Andrade has gone deeper into the -as he calls it- REAL MUSIC. That, which is made of ideas related to the social reality, and played with real instruments belonging to the real enviroment of the creator, and recorded in real time using analogic procedures at most (with very few overdubbs, punches, and so...). UNO SALE DE CASA speaks about the moment in which the every day worker or employee realizes that the best thing he could do is precisely: stop working; in other words, to stop that stupid circle of life in which there is not a single thing that is pleasant enough or leads to a satisfiying moment - in existential terms-. This is, for sure, one of the sharpest and most meaningful songs by SERGIO ANDRADE. The change of rhythm, at the last third of the song, to a baroque modern tango, it's simply amazing.
