So this is good for an almost intermediate player. Otherwise you will be at "ze" big disadvantage.
He explains a lot of stuff really well but if you don't have a foundation on which to base it much good it will do ya.
If you want to learn jazz see my jazz book recommendation which all of Richards jazz lessons could augment.
This and the soloing one especially are good in respect to octaves but also many other jazz techniques too.
Its just having it written down is so much easier to get comfortable with. The easier it is the more likely you are to enjoy practice. Richard gets bluesier in the later menu styles with some spacey, vibey guitar lines which once again are built on scales you need to know ahead of time. He also uses peddle effects and the licks themselves are up tempo and not the easiest licks you have ever tried to learn either. Still there is the jam track.
On the other hand Richard shows you how to do stuff a book just cant. So the one compliments the other. If you like this smooth jazz style then go for it. But read all my Richard Smith Reviews as there are at least three jazzy ones.
What sets this one apart is the afore mentioned guitar players in paragraph two. Those guys are all music reading pros. So is Richard Smith who attended a conservatory. I bet they even had reading material at the conservatory but here we don't get so much a a digital .PDF crumb.
Buy your chosen guitar reference book then augment it with a lesson or three. I recommend at least a couple of friendly guitar reference books. CAGED is good.
