“I remember when I first heard ‘Crazy Train’ and then its freight-train of a guitar came screaming in,” Steve Vai of the lead in an interview on the box set’s documentary. “I think it’s the first rock track I heard where the solo came in and got scared.”

“When you listen to his solos, there are moments of uniqueness,” Vai says on the new DVD. “And when I say uniqueness, I mean things that have never been done before by a guitar player.”
