ROAR by Mathias Guilbaud, 2025 / A trance beneath the surface. /

My city roars.

Like yours, it is constantly changing, driven by silent, powerful forces. Beneath my feet, an invisible metro line cuts through ruins — neighborhoods, dead ends, streets. Construction sites, machines, bodies in motion. Clatter, tremors, textures: raw, living, untamed sounds.

I walk with microphones, gathering these sounds not to freeze them, but to move through them — to hear what, amid the chaos, tries to speak differently.

These noises become stories, presences that awaken a numb urban imagination. Reactivating it is a form of situated resistance, rooted in places, cracks, and transformation.

By letting these often-dismissed sounds resonate, construction sites stop being mere breaches in the city and become breaths.

Giving voice to places in transition, reclaiming through listening a power over what slips away. Trying to bring forth another city — more sensitive, more porous — where even the roar becomes a material for dreaming. /

A sound piece built entirely from field recordings. It offers a dive into the intimate soundscape of urban change, a renewed listening to emerging landscapes where ecology is found in friction, disorder, and force. /
