Music should be a collective magic and hysteria.

We need to restore the spirit of irreverence in music.

We have to fight the past to survive.

The aim of music is not to express feelings but to express music.

I shall be the first composer in history not to have a biography.

It is not enough to deface the Mona Lisa because that does not kill the Mona Lisa. All art of the past must be destroyed.

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'.
