At the start of the 1990s, young guitarist Jason Becker was riding high, having joined forces with ex-Van Halen frontman David Lee Roth to record what would become Roth's third full-length solo album, 1991's 'A Little Ain’t Enough.'

But around the same time, Becker was diagnosed with the neurodegenerative disease amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease. Now paralyzed and unable to speak or play guitar, Becker still continues to make new music. His incredible story has been captured in the new documentary 'Jason Becker: Not Dead Yet,' which will make its world premiere March 3 in San Jose, California.

Steve Vai, who was replaced by Becker in Roth's solo band, appears in the documentary. Other notables in 'Not Dead Yet' include fellow guitarists Joe Satriani (who has high praise for 'Perspectives,' Becker's first album after losing his motor skills) and Marty Friedman (the onetime Megadeth member who played with Becker in the metal band Cacophony).

Becker is expected to attend the March 3 premiere at the San Jose Repertory Theatre. So are members of his amazingly supportive family. Becker's father, Gary, is credited with developing an eye-movement system that enables Becker to communicate with others, as well as to create new music.
