As a genre, metal is commonly considered music for outsiders. In the ending of his film "Metal: A Headbanger's Journey," Canada's most famous metal nerd Sam Dunn says as much, musing that "metal confronts what we'd rather ignore... It celebrates what we often deny."

However, take a look around you at any metal show and you'll mostly see a sea of white, male faces -- a fact that's often ignored in most discussions.
