He entered the conservatoire to study the instrument he was to research and work upon in the future. Thanks to his family, Didier was "swimming" in music from a very early age.In 1977, Didier walked out of the conservatoire, to find himself face to face with the world. At this time, he realises that music won't leave him and, feeling a tremendous desire to exceed both physically and mentally, he turns to jazz. Particularly inspired by Sun Ra and his Arkestra and Celestrial Communication Orchestra of Alan Silva in which he played for ten years, he studied at the IACP, became a teacher, then administrator until 1989.
