Cover art for Época lyrics by Gotan Project

I love Gotan Project! They are an amazing blend of styles!

To me, this song refers to the argentinian 1976-83 dictatorship... if you think about it, it makes sense..

"si desaparecio, en mi aparecerá creyeron que murio, pero renacerá" The "dissapeared thing" may refer to a person (victims of repression were called desaparecidos, or "dissapeared"), or, more generally, to the ideals of the 1970's generation, which were also forcefully dissapeared, but bound to return "renacer"...

The "rumor de pañuelo blanco" could be a reference to the Mothers of Plaza de Mayo, which use white scarves as a symbol of their fight.

In any case, it's a wonderful song.
