I've been learning guitar for about 10 months now, but my learning has lacked focus and jumped from one method to the next, and one genre to the next, trying to find something that "clicked". Like another reviewer, I also have a stack of "Learn to Play Guitar" books about a foot high. But, this is the one the finally "clicked".
It not only comes with a CD, but also a DVD, which really makes a difference in my learning - being able to see as well as hear is really important. Also, not only is the method structured, with previous lessons being drawn upon for subsequent lessons, but right from the first few lessons you can actually improvising blues lead lines. (I'm sure it'll take a bit longer for someone that's just starting out - you need to have some level of left-hand coordination.) But basically, it's just the right mix of theory and "jump-in-get-your-hands-dirty" for me.
If you think blues or blues-rock are what you want to play, you can't go wrong with this book/cd/dvd combo. I'm learning so much so fast with level 1 that I can't wait until I can finish it and go on to the level 2 book. It feels as if I'll be able to jam with the best of them in no time!! (Well, maybe the "pretty-damn-good of them" at first...)
