Yes, Murray and I have communicated privately and determined that the albums have similar (but not quite the same) titles, but have different content.

In case anyone is interested, there is an address for instructional tapes in the booket of my CD: Stefan Grossman's Guitar Workshop, P.O. Box 802, Sparta, New Jersey 07871. Available are The Guitar of Robert Johnson, The Guitar of Blind Blake, The Guitar of Lonnie Johnson, and Masterpieces of Country Blues Guitar, all taught by Woody Mann, Blues Guitar, Country Blues Guitar Solos, Bottleneck Blues Guitar, The Guitar of Mississippi John Hurt, and The Guitar of Rev. Gary Davis, all taught by Stefan Grossman, and finally, Country Blues Bottleneck Guitar taught by Dean Sires.
