Ever since 2007, the museum has invited "Sound sculptors" to appropriate its spaces during the Nuit des Musées. The development of the collection is closely linked to these events and the artists who have featured in them. In this way, a guiding principle has emerged, giving special importance to setting and the relationship with the body - physical or emotional.
Hanna Hartman,was present at Nuit des Musées 2007, Vents Dominants, with her piece, Longitude 013°26'. In 2010, the Ministère de la Culture et de la Communication - Centre national des arts plastiques, commissioned her to produce Acoustic Catacombs, an installation with sound board, for which special recordings were made in Arles. For Nuit des Musées 2010, Sons à tous les étages, Maxie Götze and Anja Erdmann created Luftikus – installation with moving fans, a work directly inspired by the Mistral and the light, two key atmospheric components of the Arles landscape. The work was acquired in 2011. For his part, Gilles Aubry, took over the whole museum for the Nuit des Musées 2011, Flux donnés à entendre. Two of his works, Rotors, 2011 and Compagnie sucrière, 2011 entered the collection at this time.
