Personally, I can't see how anyone can produce any beautiful music out of being angry.
“When I write down my thoughts, they do not escape me. This action makes me remember my strength which I forget at all times. I educate myself proportionately to my captured thought. I aim only to distinguish the contradiction between my mind and nothingness.”
“The thing I love about music is that you can take things that are painful, deep things that hurt you, and you can turn them into something beautiful.”
