Up to 2004, Bart was in charge of programming at Radio 3 / Klara (VRT, Brussels) and is still very active in producing musical recordings, his production of previously unrecorded works by Mauricio Kagel and Cristóbal Halffter being of particular note.

His diversity as a musician is an undeniable advantage when it comes to artistic supervision of recordings, as Bart aims to get the best out of the performers, allowing them compete freedom of expression while keeping to a strict schedule.
