Precious Metal's look at the history of extreme music comes at an opportune moment. According to Mudrian, metal music's earlier sounds are now having somewhat of a renaissance.
"What we're having is this movement where people are getting back to basics," he says. "You've got these bands that are making music that sounds like it was recorded 18 years ago. As things are getting more extreme and bands are getting more technical and over the top, a lot of people in those scenes are reacting and getting back to an old-school, meat-and-potatoes vibe."
