Yes! The same as in Argentina in a lot of ways. It seems that in China the music sort of reflected youth sentiment or counter-culture ideas through emotionality. On the other hand, Rock Nacional began as and apolitical music movement but then later on became codified/ideologized at the festivals through reporting on the harsh, unemotional reality of the situation in Argentina. (This can be seen in lyrics that directly mention the country's sociopolitical problems and their effects but not necessarily the emotions that result from said occurences.)
