I gave this the full star rating even though it it's doubtful that I will ever have any intention of working systematicaly through the theory. If one didn't know John Miller's musical excellence as a guitarist through his solo and ensemble recordings going back years, as well as his excellent, meticulously presented more recent instruction DVD's, then it is probable that a first time introduction to him through - at least the first DVD in this set - would faintly bemuse and dampen enthusiasm for blues, Country blues and ragtime guitar. Therefore I would recommend initially to play the second DVD with the excellent tunes first and see where the whole package is leading too. Become excited about it and then turn to the theory step by step on the first DVD. Miller teaches in his usual kindly old world fashion - with white board and pen this time - and it faintly bemuses if one doesn't remember what an absolute ripping, versatile guitarist he is and has been. Deep musical knowledge works for him and his range and verstility of guitar performance are all the more impressive because of his musical education. The trouble he has taken to share much of it through this DVD set should benefit dedicated budding young guitarists who want to be a bit exceptional a great deal I would think.
