Ouro de Tolo
"Ouro de Tolo" is a song by the Brazilian singer and composer Raul Seixas from his first solo album, Krig-ha, Bandolo!. In 2009, it was chosen by Rolling Stone Brasil as the 16th best Brazilian song.
The name is a reference to the promises of fake alchemists from the Middle Ages. Seixas criticizes the wishes of the middle class who supported the Brazilian Miracle on the Brazilian military dictatorship saying that the conformist and religious views, such as the euphoria of the middle class citizen, were like a fool's gold.
Thus, transposing to Raul Seixas' own ideals and aspirations at the time, one can see that he indicates that the real gold was in the awakening of individual consciousness, aimed at building the Alternative Society, and not in the ufanistic and triumphalist discourse of the military dictatorship of the time. Therefore, the flying saucer at the end of the lyrics would be a reference to this new society to be built.
