How much soul to you play with?

To me that alone stands the blue's out from the rock. What I mean is watch a clip again thinking about how much soul they play with with say Slash or Jimmy Page, the list is endless of course. To me, most of todays metal was driven by the agression of early punk as rock was driven by the blues. That doesnt mean that guys like Dime or Zakk Wylde just for example didnt play with a ton of soul or that metal is all agressive punk rooted music. This is just how I see things from a generic point of view. A once over if you will before you'd really begin to break something down.
