Pierre Boulez Quote
Why compose works that have to be re-created every time they are performed? Because definitive, once-and-for-all developments seem no longer appropriate to musical thought as it is today, or to the actual state that we have reached in the evolution of musical technique, which is increasingly concerned with the investigation of a relative world, a permanent 'discovering' rather like the state of 'permanent revolution'.
