Birthday party
violinist in New York

A milestone deserves more than a playlist: one artist, a glowing transparent violin, and the songs that tell their story — played live.

Among the private requests that reach Sadie, one keeps coming back: a birthday someone wants to make unrepeatable. A 40th on a Manhattan rooftop, a 60th in a private dining room, a 30th that turns into a dance floor — the shape changes, the intent doesn't. Somebody in that room matters enough for live music.

This is where her story earns its place. Thirty years of violin, begun at age three in a Paris conservatory near the Eiffel Tower, now played through a one-of-a-kind transparent instrument that glows through the dark, in a couture dress of light. For your guests, that means a show they will film; for the person you are celebrating, it means their favorite songs — the ones that mark their decades — learned beforehand and played live, to them.

The format bends to the party: classical violin over dinner, the glowing show at the cut of the cake, electric violin over the DJ until the end. And if you want the whole thing to be a surprise, the entrance is engineered with you — down to the minute the lights go out.
