Schrödinger's cat may have nothing to do with this. It doesn't matter if, inside the box, the cat is alive, dead or undead. It is a paradox. Still, a film about a Portuguese rock band can begin with an introduction to quantum physics, when some of these basic concepts are used as a starting point for the creative process. The director Ricardo Oliveira recorded the daydreams of recording the third album of originals by Capitão Fausto: Capitão Fausto Têm os Dias Contados. And when in one of the songs - “Corazón” - is heard at a certain point: “… Pontas soltas. Isso é comigo. E por isso queres também ser assim. Pontas soltas. Isso é comigo. Para estragar um disco tenho-me a mim…”, it is clear that the band of Tomás Wallenstein, Manuel Palha, Francisco Ferreira, Domingos Coimbra and Salvador Seabra reached the age of majority and tied such loose ends. More than a diary, it is an experience.
