Nuevo Tango Rave NTR The NuevoTangoRave is and always has been an avant-garde, anti-elitist and visionary tango event and a platform for innovative artists. NTR is a solidarity event and is conceptually based on Osvaldo Pugliese's solidarity orchestra model, which is based on (gender) equality, caring, innovation, personal development, improvisation, fun and the right to make mistakes. Obligatory rondas and cabeceos, tandas cortinas have no meaning in this concept. More Info below.
