Bart Callebaut

Bart Callebaut was our main music man in Leuven for more than 30 years and also the inspirer of our annual a cappella party CLOSE Festival. So he knows WISPER like no other, and is the ideal driving force behind our diversity policy. Uses a lot of words, likes to unite everyone around a pile of musical instruments or a polyphonic song and leads his own choir in Mechelen: Les Amis de P.
