Confesiones de Invierno (Winter Confessions) is the second album by Argentine rock group Sui Generis, released in 1973 by the Talent label.

There are several versions of the origin of "Rasguña las Piedras", the most popular song on the album.

Some time later the body was exhumed and when they opened the coffin they found that the lid was scratched showing that she was buried alive.

Is it true you wrote "Rasguña las Piedras" in honor of a girlfriend who had catalepsy?"

I was living with María Rosa Yorio in a cheap hotel and she went to buy potatoes or something.
