At the age of ten, Wim Bex started to play the trumpet. Four years later, he swapped this instrument for a trombone. During his studies at the Lemmens Institute, he completed his training with a bass trombone. Currently he plays as a freelance musician for various orchestras such as La Monnaie, the Brussels Philharmonic, Hermes Ensemble, the Limburg Symphony Orchestra, l’Opéra Royal de la Wallonie and Flanders Opera.
As a composer, Wim Bex is entirely self-taught.
