Stéphan was born in Marseille and plays vibraphone and percussions. He has played notably with Big Four, Rétroviseur and Dawn. He also shares the road with Raphaël Imbert, Olivier Goulet and Sophie Alour. He is sometimes called to record with Hervé Sellin or the Ping Machine big band. After getting a degree from the jazz section of the Conservatoire National Supérieur de Paris, he changed sides and now teaches in Montreuil and Vincennes. He wears tennis shoes with no brands and had his first thrill in front of a painting by Delatour.
