"There is no reason why a guitar player makes the guitar-playing faces," Biersack says. "It doesn't help you play guitar. You've not improved your skills. It's because you're up onstage, and the natural inclination is to put on a show. The rock guy faces are just as much of a front or a show as us wearing crazy makeup. It's just a different scale."
For Biersack, 22, this outlook all began when he was a little kid who happened upon his dad's stash of Kiss trading cards in the basement one day.
