Tired of the same old unadorned I -IV -V patterns you've been improvising over? You'd be amazed at how far composers have departed from the basic blues pattern in their compositions; substituting chords, adding chords, adding extra measures and the like. Within these pages you'll find some of the great blues chord changes of all time. You won't find any melodies here; just unique and challenging ways to make you a better improviser. On the CD you'll find recorded versions to solo over.
