Frederic Rzewski, in Contemporary Music Review (2006):
There are very few things in the music of this century whose importance is so universally recognised, and about which so little has been coherently written.
It may be that the difficulty of speaking about improvisation is structural, as in the art of magic: The trick itself is the thing that is interesting. The explanation of the trick, although it may also be interesting for the insight it offers into the magician’s craft, somehow loses sight of the essential experience of magic.
