"Ultimately your playing will only be as good as your rhythmic drive is solid" - a (profound) quote from the beginning of this fine book. The rhythmic drive is established by the stomping foot & the alternating bass in the right thumb. The book then superimposes gradually more complex melodies & counter rhythms on top of this fundamental alternating bass with the three main fingers of the right hand - each finger dedicated to a particular string of the guitar. Always geared to playing actual 12 bar blues rather than just technical exercises, this book methodically & relatively painlessly takes the student deeply into this intricate & beautiful music - introducing hammerons, pulloffs, slides, bends, heel damping, walking bass, vamps, turnarounds etc. The accompanying cd is wonderfully inspiring. On it Mark Galbo talks & plays you through each section of the book, emphasising & demonstrating the importance of the solid alternating bass as the music gains in complexity. You'll find yourself listening to the disc for pleasure as much as for enlightenment. The book ends with 5 actual blues pieces in the styles of various great players (Robert Johnson etc). I honestly can't think of, or even imagine, a better book to get you started with this style of guitar - pure communication - from & to the heart!
