Honestly, I'd really recomend Scenes.... my dad even loves it! Spot on about Vai, He is such an amazing player but like you say, in a band context (with David Lee Roth was also great!) Jason Becker used to play in cacophony with Marty friedman (ex-megadeth.. also my all time favourite guitarist). But he was apparently better than Friedman, and released a couple of solo albums before his disease (amyotrophic lateral sclerosis) badly kicked in -and basically ate his muscles so he couldn't play anymore. the cacophony stuff is pretty impossible to get a hold of... but solo albums not so much. I'm not overly familiar with his actual songs so couldn't recommend where to start but I've heard his playing and it is very good P.S. even Marty Friedman's solo albums are shit....
