In high school, when my friend Dave and I were trying to think up names for our still-incipient metal band (final choice: Christkicker), we postulated a theory akin to "peak oil". That is, there is only a finite supply of metal names, and they were being used up at an alarming rate. By the mid-90's, the metal world would be thrown into chaos and confusion. (But not the metal kind of chaos and confusion, you understand!)
Wait, does that make me responsible for nu metal? What an asshole!
