Walter Salles' segment, "à 8944km de Cannes", shows the duo Caju & Castanha singing the traditional northeast Brazil rhythm "repente". Repente is an improvisation singing in rhythm and poetry like RAP and Hip Hop's battles where each musician creates the verse (in an specific kind of verse, rhyme and rhythm) as it's singed. Each singer answers the other's verses as in a battle of words. The goal is to keep until the other cannot create a rhyme as quickly as the singing (as the speed of the rhythm grows faster and faster). It's an specific folkloric music from northeast Brazil.
In the segment "À 8944km de Cannes", Walter Salles uses as title the exact distance between the small village of Miguel Pereira (at the State of Ceará, Brazil) and the glamorous city of Cannes in France. The characters, after the singing battle, talk about Cannes being an small fisherman village before some smart guy started the film festival.
