For many years he was one of the driving forces behind the band The Ex.
They received large international recognition for their unconventional interpretation of music and their consistent political attitude, their ‘organic way’ of making music and the fact they kept their independency from the big commercial music-business.
After they won the national dutch pop-price ‘BV POP’ in 1991 this appreciation only got bigger. The Ex worked also with a large variety of artists and musicians including Han Bennink, Ab Baars, avant garde cellist Tom Cora, Kurdish singer Brader, the Malian group Lanaya but also toured with pop groups like Sonic Youth, Shellac, Chumbawamba, Tortoise & Fugazi.
One of Luc Ex’s last projects within The Ex was the spectacular orchestra EX ORKEST: a 20 piece bigband with an enormous sound, dynamics and energy. Lyrics were written by the dutch writer and ex-soccer player Jan Mulder (Ajax, Anderlecht).
