I've just recently gotten back into playing the guitar, and am looking for a course that will allow me to focus my practice time. I've seen that "Metal Method" appears to be a popular one, but was wondering if there was something that focuses more on the heavier metal styles (rather than hard rock.) I'm also interested in learning more about the guitar and music in general, so it would be great if it included some theory. Any other links, websites, and resources would be greatly appreciated. Thanks all.
