i unapologetically love Steve Vai!
i've seen him live a few times, and he's a great entertainer. of course he's the star of the show, but every band member also got their moments in the spotlight. and the music is always amazing.
i have always found his music much more interesting and listenable than other virtuoso guitarists. while Satriani has some great tunes, he generally bores the hell out of me! :)
i'll never be able to play like him, and i have no desire to slavishly buy all his gear, but he did inspire me to get a Fernandes sustainer, which is great
