The first versions of the song was based on the acoustic guitar and a keyboard synthesizing an accordion, over which Russo tried to sing. He struggled to find a melody line and ended up recording many channels with his voice, making the music base and the lyrics so chaotic. The text became so scary that made guitarist Dado Villa-Lobos and his wife Fernanda fled from the studio after they read the written words.
The mixing was also hard, since Russo would never be satisfied with producer Mayrton Bahia's work. The situation reached a point to Russo turned off the sound and Bahia threatened to finish the album without him. Russo didn't say a word and then he said he liked the final result. Villa-Lobos, on the other turn, cried when he listened to the song's final version.
