Justin Sandercoe will teach you how to play The Blues on your guitar for free online.

You can donate to Justin’s website or you can buy a DVD version of his teaching if you want higher quality video.
If, however, you’re poor — but you somehow have a good internet connection — you can learn a lot of Blues from Justin for free:
As you can see, Justin’s teaching style is calm and direct and his examples are exemplary.
I highly recommend Justin Sandercoe as a virtual Blues guitar teacher — and he also has lessons available for playing Jazz, Rock and Metal — and he’ll even teach you how to write a song or two if you’re in the mood.
Wow. Great site, David. I will certainly be using his lessons in the future! 🙂
Sounds cool, Gordon. Let me know what you find and if you need help!
