I remember reading an article on vai.com years ago, where he talked in length about finding good mimics and gestures for certain riffs and licks and practicing them in front of a mirror,
so yes, this stuff is surely kinda "choreographed".
But I really get to love this,
sure, it looks completely bonkers, but I dig the dedication and passion that shows.
I mean, many of us are happy to fumble through our usual set of songs on stage,
and he takes so much freedom to practice weird dances while playing amazing stuff...
Weird, but insanely cool.
