[silence] Young Cage

[Stefano Pocci]

Hi there, sorry if this sounds a bit silly but I was wondering if there 
are any news available of John Cage's childhood....his first 20 years, 
let's say. I'd like to understand the birth of John's maverick spirit. 
The causes and the environment that produced such personality and ideas. 
Any clues? Books or links on the web I could have a glance at?

Thanks in advance

Stefano
