Released in 2012 on Another Timbre, Chantier 1 juxtaposed two studio recordings with five from a construction site tasked with erecting the Philharmonie de Paris. The idea was that Pascal Battus and Bertrand Gauguet would try and recreate the on-site recordings in a "neutral, silent space" by memory. This served as an interesting exercise that ultimately pointed to the richness of the construction site's own sonic identity, especially since the studio tracks were unexpectedly placed at the beginning of the album. In Chantier 2, Gauguet wrote that the chantier had its own autonomy, and that his and the others' presence had little effect on its "life." As such, there was little intent to "musicalize" it; to do so would undermine the detailed sound world already present.
