MC WAX presents single with his new work "Esgoto". The music is quite engaging with low frequency synthesizers, vocals and vocoder effect with a bass line electro. The theme is quite dirty, treating sewage and their fate in the environment. Causing various diseases can be considered the villain in the health crisis. We give due importance to this matter, since it requires large investment by the public and private society. Health in Brazil and the world will only improve if the conditions of access to sanitation are met.
