Director Chantal Akerman and cellist Sonia Wieder-Atherton closely worked together on more than 20 films. Ostrovsky rediscovered an older video of the two leaving a brasserie in Montparnasse, which then called to mind that all three of them had New York, Paris and Moscow in common. In turn, this prompted Ostrovsky to focus on the sound work in Akerman’s films.

Son Chant, a 12-minute short film about women in a traditionally masculine environment, was made using a small video camera, a mobile phone, and footage shot on Super 8. It all started with the above-mentioned video recording, which American artist and curator Vivian Ostrosvsky has called their farewell to each other. Akerman died in 2015; the following year, in remembrance of the Belgian filmmaker, Ostrovsky made the short film But Elsewhere Is Always Better.
