The "must have" skill of every real lead guitarist

“The Blues? It’s the mother of American music. That’s what it is - the source.” (B.B. King)

Blues is a “must have” skill every real lead guitar needs. You might not be a blues player, however, from the guy jamming at your local pub to the Jazz master improvising in the theaters: they all have the blues as their source. And if you play blues well, you can play everything else well. That’s it!
