The soundtrack for the animated film Arco (directed by Ugo Bienvenu, winner of the Annecy 2025 Crystal Award for Best Feature Film, also presented at the Cannes Film Festival & co-produced by Nathalie Portman) was composed by Arnaud Toulon. Between orchestral flourishes and delicate electronic touches, he composes immersive, sensitive, and luminous music that evokes the great scores of Joe Hisaishi while asserting a resolutely contemporary identity. Conceived as a true sonic journey, the soundtrack accompanies Arco's temporal wanderings with rare cinematic intensity. Each piece oscillates between poetry and dramatic tension, making this work an experience in it's own right, to be discovered far beyond the images.
