Jason Becker is one of my favorite players, try checking out this site : http://www.saunalahti.fi/angwie/

Lots of tabs and mp3's there. Also some info on Jason.
Heres another very cool one : http://members.theglobe.com/jasonbecker/jason.html?nfhp=935864499

I know Jason has an official website, wich i cant find right now, but it shouldnt be too hard to find i guess.
