The second doc from Sam Dunn and Scot McFadyen, on metal delves into the effects of heavy metal music around the globe. It is very interesting and again told via Sam Dunn's travels to meet some of his heroes, and in this case, to develop new international heroes in places as unlikely to find metal music as the middle east, and China. Doesn't hurt that he manages to yet another shot in about the whole Metallica VS Napster thing, directly to Lars from Metallica, when it comes out that the only reason some of these countries have heard metal is by "illegally" downloading music, including Metallica. Well made. Can't wait for another doc from these guys.
