John (not so) Caged

Perhaps they'd produced a piece called the "prepared orchestra", where every instrument adds materials to drastically change the original timbre.



This second is better sounding to me. Why? The timbre produced by the individual notes are clearer (perhaps more carefully prepared), hence giving a certain idea which the performer seems to want to drive at. Compared with the first, which was too "random" for my taste, this recording is more telling.

And there!

Leaving the creation of the piece to the audience!
