Guns and Roses was a global phenomenon, and they bended the arc of music history by burying the cheesy and phony hair bands of the 1980s.Big deal, they are grossly overrated as well. Sweet Child of Mine is good but not much else.
G&R, Metallica, Nirvana defined rock music for at least a decade.
And Slash is on record pointing to Aerosmith as the model and inspiration for G&R.
