There are several versions of the origin of this "Rasguña Las Piedras" : One version says that Charly had a girlfriend who was "dead" (catatonic) and buried. Some time later the body was exhumed and when they opened the coffin they found that its lid was scratched showing that she was buried alive. This version was believed by Charly Garcia. Another version says that this is a hymn to the military coup of 76 in Argentina. The story of dead, missing and detained in secret, where they were locked up in solitary confinement, with his hands tied and blindfolded, listening hour after hour as others were tortured. However, this song was written a few years before the coup. Another is the love story between a boy and a girl, in which the girl was crushed by a wall, and the protagonist narrates what is happening and its impotence to save her. She scratched the stones to leave, he listens and tries to do something, but can not. The truth is that everything is clarified in an interview with Charly Garcia by Felipe Bianchi in 1993: "For the last time. Is it true you wrote "Rasguña las Piedras" in honor of a girlfriend who had catalepsy?" "I have no idea who came up with that. Really. There are even more versions. They also say that my sister was dead. Nonsense! It's a myth. Neither catalepsy or anything. The song is pure poetic fantasy and it was done on a regular day. I was living with Maria Rosa Yorio in a pension and she went to buy potatoes or something. When he returned, the song was ready"
