That would be a kick in the pants then (for Joe). Anyways, I think faav's quote hits the nail on the head. Steve out does Joe in every aspect, and his only failure is that he can sometimes go overboard, creating experimental nonsense which leaves our ears crying out for the relatively easy listening Always with Me with You.
However, I said it before, and I'll say it again; get the video of Tender Surrender. To me, it was a religious experience. Maybe it's just me. Steve Vai has set a standard for guitar players, though... I wonder if he'll ever be topped.
