When the “forced disappearances” became systematic under the argentinian military dictatorship (1976-1983), the aim was not only to kill its opponents, but also to inflict a reign of terror and silence on the whole society. But the families of those who disappeared resisted and art became an important element in the struggle against this unspeakably paralyzing regime. Music became a way to reassert the sense and symbolism which had been destroyed. And this process generated an alternative to terror. Using a mixture of rock and murga, the music portrayed mutual sufferings. The emotions transmitted reversed the intrinsically negative character of the unspeakable and transformed it into a positive force. This music conveyed a form of knowledge beyond words, it made sense via the senses. It allowed the victims to come together and to reinvent a feeling of sense which they could subsequently offer to the whole of society.
