This has been sitting in my cupboard on a VHS tape for the last 30 years. It was always one of my favourite bits of video and on watching it again I can see why. Steve Vai is on fire! Possibly the most inspired I've ever seen him. That solo at 14:20 and 12:00!! WTF! The descending lick at 14:53 is possibly my favourite ever Vai moment. I watched this so many times when I was a kid.
I've been hoping that somebody else would post a good quality version to YouTube, but it never happened. Maybe this will inspire whoever owns a better version of it to share it. I only just realised it was from the Chicago NAMM show.
I also have the Racer X, Vinnie Moore and full Joe Satriani set. All great but this one really blows my mind.
