Watch the The Rev online guitar lesson by Jeff McErlain from Essentials: Solo Electric Blues
I could play a blues like this for hours because there are so many options and directions I can go within the framework. I will say once again that the main element is playing in time! Time is everything, groove is everything. It has to sit right and feel good for it to be
good! As I continue to mature as a player (hopefully) this becomes clearer and clearer and more important to me. Play this C blues without the fills and concentrate on the feel. The great thing is the better you get at it, the more aware you become, the more fun it is. I find it to be one of the most satisfying aspects of music, sitting in the middle of a great groove.
