I've seen the rock discipline but its too hard rock metal and modern for my taste.

I was wondering if there any other good finger exercise dvd's out there that will instruct me like Petrucci does but for blues.

Paul Gilbert. His instructional vids are pretty good, and with his sense of humor they are hilarious.

Junior's usually at least a little terse, but he knows his stuff. I've always read his posts in a grouchy grandfather voice, a grouchy grandfather with a huge stiffy for alternate picking.
Besides that, he's right this time. As usual.
What are you trying to gain from these instructional videos? Speed, technique, licks, basic overview?
