Metal Method, as in the one by Doug Marks? That one is great (the whole six video course). It really teaches you a lot of stuff, and in a way that you don't have to like speak another language to do it (as in be really experienced with this stuff). By the end of it, your learning this really cool solo. At first I was skeptical with it (when I started it a year or two ago), but it is really good. I got my moneys worth. It also taught me basic modal theory, in an easy way.
