Bruno.

Bruno grew up in a housing block on the outskirts of Montpellier. Third floor, thin walls, and a neighbor upstairs who had been a DJ. At fourteen, Bruno had spent weeks listening to a vibration coming down through the pipes and walls — not the song itself, but something harder to name. One day he went up and knocked on the door. The neighbor lent him a pair of Sennheiser HD 25 headphones (the ones real DJs use, not the thirty-euro ones from the supermarket) and Bruno put them on and listened to the same song he'd been sensing through the concrete for weeks.

It was something else entirely. The distance between the kick drum and the voice. The air inside the mix. From that day on, he stopped listening to songs and started listening to sounds. The headphones still hang on a hook by the door of his current apartment. They no longer sound good, but they're still there.

There's something in that image that connects with anyone who has discovered a passion unexpectedly. Bruno didn't go to a music school. He didn't have a teacher guiding him. He had a thin ceiling and enough curiosity to go up one floor and knock on a door.

In high school, Bruno got tens in music without studying and scraped passes in everything else. A technology teacher let him use the auditorium sound system for an end-of-year festival. Bruno spent three weeks preparing that room: he placed cardboard and fabric to control the reverb of a space that normally sounded like a cave. He calibrated the speakers with a borrowed microphone and free software. The festival sounded decent for the first time in the school's history.

Nobody congratulated him publicly. The teacher told him in private: "You have an ear. Do something with it."

That sentence changed everything. At eighteen, instead of going to university, Bruno took a train to Marseille with a backpack and the address of a studio looking for an assistant. They paid him minimum wage to load gear and roll cables. He didn't mind.
