I felt very humbled watching this doc. Jason Becker was a guitar prodigy in the late 80's who is now virtually paralysed with Lou Gehrigs Disease
Amyotrophic lateral sclerosis - Wikipedia, the free encyclopedia and is still alive 20 years later despite the life span of the sufferer being 5 years. He still makes music through the use of his eyes (watch the doc) and is a genuine inspiration to so many people.
I have to say that his parents are two of the most inspirational and gutsy people I have ever come across.
You don't need to like Metal to watch this doc at all. Class stuff.
