I have been teaching and arranging for guitar players for a very long time, and one of the problems I repeatedly encounter is the red hot lead guitarist who can't play rhythm worth a bean. I have to explain that even if it's your group, you will spend two thirds of your time playing rhythm. Then I have to convince them that what they are doing is awful, and believe me, it is. The most popular method is what I call "the thrash". The way I make the problem clear to them is to play backup myself while they take a solo. Then I point out that if that kind of rhythm is what they want, THEY have to be able to do it too. Then we start in on Mccabe's book. The Cd's numbers are screwed up, but you can figure it out. (I doubt if the author is responsible) I love this book. Before it came out, I had to do demo tapes to show what to do. Now I just write down the page number. Six weeks of serious work will make you better. Six months of work will make you a lot better, and very popular with your fellow musicians. Make no mistake; this book is aimed at blues and rock. If you are working in that field and play guitar, get this book. If you are working in this field and play some other instrument, you might want to suggest to someone in the group that he buy it. Self defense.
