I have quite a few instructional books for blues guitar. This book "easy blues Songbook" by Ed Lozano is by far my worst purchase. Mr. Lozano's voice on the accompanying CD is absolutely horrible. Sooooooo phoney! However, the tracks featuring Veronica Stolze are another story.
The CD track listing is located at the front of the book before the table of contents. The pages containing the music, however, do not list the track number. So, you have to flip back and forth to find out what where you're at.
If you're a beginning guitarist, don't be fooled by "easy blues". It's not. Save your money and buy something else. Any thing else. A good place to start is with "Blues You Can Use" by John Ganapes.
