This project was created to introduce audiences to certain Latin American songs that are deeply rooted in French culture but are generally unknown to the public. The most well-known songs include "La Foule," originally a Peruvian waltz by Ángel Cabral; "Lambada," originally a Bolivian song by the Hermosa brothers; and "Alouette Alouette," originally an Argentinian song, among many others. The project's name is also a tribute to all the arrangers involved in musical projects of various genres, who often work behind the scenes but are essential to achieving the desired artistic goals.

The musicians involved with this project are percussionist Minino Garay, saxophonist Baptiste Herbin, Léo Montana on piano, Felipe Cabrera on double bass and bandoneonist Patricio Bonfiglio.
