Great post @undeniable, really.
I've seen the Guns at the Werchter Classic festival (Belgium) this year and frankly, it was amazing!!! The show lasted 3 hours, yes 3 hours of pure Rock and Roll!!!
And despite what some people said, Slash is a f...ing guitarist. Close your eyes and listen to his soli... it's incredible!!
And I know why he is considered as one of the best guitar player in the world : he really plays with his heart, with his soul, not only with his fingers. And that makes all the difference, and you can feel it...
