When we talk about interiors, we think about light, materials, the color of the walls. Rarely about sound. Yet, a room can be heard as much as it can be seen.

Julien Boulfray knows this better than anyone. A professional musician turned artistic director, he creates sonic identities for brands with his agency, Phantom Punch. In his life as in his work, sound is never a detail: it's what defines a place, a mood, a person.

In this episode, he speaks to us about his relationship with sound and acoustics, but also about sharing, transmission, music as a refuge, and a universal language.
