Stevie Ray comes a distant second--- I still thank him for leading us out of the 80's techno-crap and back to blues-based rock-n-roll, if only for a while. What passes for such today has no tie to blues, which is where rock-n-roll came from:cry
(I remember, in the 6th grade when that song came out, our music teacher spent like 2 weeks discussing it--the guy spent like YEARS writing it)
