Through the second half of the 1960's the Beat movement and the first National Rock were the flagship of the youth, leaders as never before of a society in transformation. The formation of the first bands, the venues for concerts, the difficulties to sing rock in Spanish and interact with other artists create new ways to communicate previously unavailable. This documentary presents the story of these first pioneers of the Argentinean rock music.
