Christian Boltanski’s exhibition ‘Animitas’ has recently opened at the Noguchi Museum in Queens, New York. The artist’s famous outdoor sound installation is  part of an  elaborate series of works that Boltanski named after the small altars that can be found at the side of the road in Chile, for example, in memory of victims of accidents and in honour of saints, where they are called ‘animitas’ (‘small souls’). Made from countless Japanese bells it fills the museum’s garden with ‘music of lost souls’.
