As I started to say, this is a must have if you're on that never ending journey!
...Many of us came to this point from the likes of Led Zeppelin or countless others that had their success recording many great blues songs. Only thing wrong back then was that we didn't know just how white we were (even if we had the blue) ! Its no wonder bands like that had success...
However, once you noticed any credit being given to whom ever really deserved it (nothing against Jimmy Page or Eric Clapton) it starts.
I'm talking about being hungry enough to go back, and back again, just to find their influences, etc etc... the journey, the true road.
No, Robert Johnson didn't start it, but he sure got my attention, and these recording artists where his mentors on his journey, back to the crossroads!
