Translation of dialogue at the end of Part 1:

Emmanuelle K: John Cage thought it might be necessary to write a score to describe things which are not incompatible at all with what I've just listended to.
Jean-Jacques Birgé: Our score deals with improvisation, but that's not what we do. Our methods for writing music might be a little different from the time when Cage wrote his part. We call our works "instantaneous compositions" in opposition to "preliminary compositions". Why would Cage sign a score which we have composed from A to Z ? The author rights belong to us !
