[Clemens Gresser]

Hi there,

Coming in rather late on this one, but if you can read German, the
following might be worth a read:

Thomas M. Maier
Ausdruck der Zeit. Ein Weg zu John Cages stillem Stück 4'33''
19.50 EUR, ISBN 3-89727-102-8, 198 p., 2001
(description in German on http://www.pfau-verlag.de/shop_detail/27102.html)

Best wishes,
Clemens
