Back in high school in the late 1980s, my friend Dan really liked the band Stryper. He cut the sleeves off his jean jacket, drew the band’s logo in Elmer’s glue on the back, then threw gold and black glitter at it to make the only Stryper vest any of us had ever seen. We teased him mercilessly. Why? Because Stryper was a totally cheesy Christian glam metal band from Orange County that sang about Jesus while wearing mascara and yellow spandex, and that seemed the most un-metal thing possible to a bunch of teenage hippies and metal-heads in 1986.
