Born in 1953, Jean self-teaches himself guitar from 1966. He puts his first band together and starts composing in 1970. He turns professional in 1972, playing for dance bands in western France. He is the founder of several combos from 1976 to 93:
- Noëtra, with, notably, Christian Paboeuf (oboe) and Pierre Aubert (violin). The band grows, counting up to eight musicians. From 1979 to 1982 Jean composes and records all of the combo's repertoire, which has been published on three CD's for Muséa Records: “Neuf Songes”, “Définitivement bleus...” and “...Résurgences d‘errances”. In 1983 the octet becomes a quintet and plays the “Dunois” in Paris. The same year they record a live concert on French public radio. The recording is released as a Muséa CD in 2010.
