I have been playing for over 20 years (not continuously) and I feel like I have hit a ceiling. I have tried to improve my speed with online lessons, youtube, books, etc, but I find that it's tough to stay disciplined with those approaches, and there's so much out there it's hard to know what's good and what isn't. My goal is to really improve my technique and speed in a blues context. I don't need to be Yngwie fast, but I would like the ability to bust out some speedy, tasty blues licks/runs a la Kenny Wayne S, SRV, Johnny Winter. I have decided that taking lessons again would be a good idea. Haven't taken any since I first started out as a teenager. Does anybody have any recommendations for a good blues guitar teacher in either Chicago or the North or Northwest suburbs? Sorry if this isn't posted in the right forum -- this didn't seem to fit in the other forums.
