Radio 3 it to air ‘silent symphony’ by John Cage.
Larry J Solomon has an indepth essay on the subject here
I imagine it’s something that you have to see performed rather than ‘listened’ to at home. It’s a bit like looking at a Rothko or Fontana on screen or in a book, rather than standing in front of them in a gallery.
Fontana’s work looks rubbish when reproduced, yet commands your attention when seen in the flesh. Much like 4’33′ I’d imagine. Or it could be shit; punctuated by retired colonels coughing in the audience or the fidgeting of the person next to you?
Silent Radio, or empty, but well lit galleries, blank canvas’. what next, minimalist webpages ?
