I suggested that it was not enough to add a moustache to the Mona Lisa: it should simply 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'.

Music should be a collective magic and hysteria.

The function of pop music is to be consumed.

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

We need to restore the spirit of irreverence in music.

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