Despite the glam-hair aesthetic and heavy guitar riffing, Bon Jovi stood out from the hair-metal bands of the day in a number of ways. Dig just beneath the slick surface of “Slippery When Wet” and you’ll find mainstream hits like “Livin’ on a Prayer” or “Wanted Dead or Alive,” which eschew the overt sexual swagger of L.A.’s Sunset Strip in favor of something slightly deeper. It’s no wonder the band has enjoyed a longer and more prosperous career than most of its counterparts, much of that success originating with this massively popular album.
