This book is everything you need to get on your way to becoming a blue's bass player. If you already play blue's and know quite a bit about it then this is not for you. This book show's the very basic information on blue's bass playing and cover's everything from tuning your guitar to 12 bar blue's playiing minor and slow blue's etc.... The book did include a c.d which was helpful because it had commentary on there from Roscoe Beck who is a well accomplished blue's bsass player. The only problem with this was that between changing track's the band played a little blue's song which didn't really help in my learning of blue's. My favourite aspect of the book is that it build's you up easily from 12 bar blue's through to more complicated stuff but not to hard as so it's very hard to learn to play. Overall this book taught me a lot on blue's bass playing and has encouraged me to buy other book's by the same company.
