"Cantata de puentes amarillos" is the song in which the influence of Artaud's writings are most evident. Due to his reading of Artaud's Van Gogh, The Man Suicided by Society, Spinetta came into contact with van Gogh's letters to his brother Theo and incorporated several images from them into the song's lyrics. For example, the "yellow bridges" (Spanish: "puentes amarillos") are presumedly inspired by Langlois Bridge at Arles, his only painting featuring a yellow bridge. Furthermore, van Gogh's painting Road with Cypress and Star is referenced in the lyrics: "Those shadows of the blue road/Where are they?/I compare them with cypresses that I saw/Only in dreams" (Spanish: "Aquellas sombras del camino azul/¿Dónde están?/Yo las comparo con cipreses que vi/Solo en sueños"). In one of his letters, van Gogh reflects on the suffering of a caged bird that has food and health, but still longs to be free like the other birds. This inspired Spinetta's lyrics: "Look at the bird, he dies in his cage" (Spanish: "Mira el pájaro, se muere en su jaula").
