hey
its from a guitarist called Chris Impelliteri on his Stand in Line album in '88
He was also in the band Impelliteri.

it has been labelled loads of different guitarists.
Satriani,Steve, Vai, Richie, Yngwie Malmsteen to name a few.

it is still a great instrumental. i couldn't believe it when i got one saying it was richie. i know richie is amazing but i have no idea if could play that technical kind of stuff.
