Description:What is written and recorded here is "gold" for any beginning/intermediate blues guitarist. You will learn interesting comping patterns and fascinating chord substitutions to make your blues rhythm playing much more interesting than the standard I7-IV7-V7. However, at only 16 pages and less than 30 minutes of playing on the accompanying CD, it is fair to say that this package is parsimonious (to be kind). Double the length would be fair for the price. So, what you get is great but not nearly enough. "All Blues for Jazz Guitar" by Jim Ferguson covers similar ground but in far more depth and detail.
