Guillaume Connesson is without doubt one of the most important composers of the 21st century. His very diverse repertoire (from orchestral and vocal to ballet, film- and theater music) is performed regularly by the world’s top orchestras.

“Guillaume Connesson really knows how to write. His scoring is brilliant, but more importantly he has ideas. He writes tunes and motives that are attractive, capable of development, and individual.”
