A series of entertaining instructional programs illustrating both scale & chord voicing's made recognizable by the world's greatest guitarists, this release focuses on the one and only Robert Johnson. Robert Johnson, the man who met the devil at the crossroads and sold his soul to play the Blues. Enjoying little commercial success or recognition, it was only after his work was reissued on LP, over 20 years after his early death, that Johnson's music reached a wider audience. Now rightfully regarded as a master of the blues, Johnson is credited as a great influence by many Rock musicians.
