Jason has ALS and can only move his eyes. He still makes music by writing it out with help of software.

I'm sure a post about Jason would be interesting, but I'm too occupied to do it.
Thanks for mentioning Jason and Marty, two really talented musicians.
Yeah I added him to my last blog in this series along with Marty Friedman, and Jake E. Lee
