The one section that you absolutely must not miss is this one:
One person who was very moved by Gorecki’s third symphony was a 14-year old girl from Sweden ”” a burn victim who wrote a letter to the composer, telling him that his music was the only thing that kept her alive. Gorecki reads from the letter in his interview.
There is an audio link where Gorecki reads the letter through a translator–it made me cry–KSH. (Hat tip: Elizabeth)
