A mob swarming with authority figures dominated by the stony gaze of an all-seeing, unblinking eye engulf this stark poster for Billy Idol’s song, “World Comin’ Down.” From the 2005 CD “Devil’s Playground,” the tune is a Molotov cocktail of angst and anarchy that features the singer gnashing his way through the vocals in time with an onslaught of jackhammer guitars. Brimming with attitude and backed up by killer songs, the UK native grabbed the brass ring of stardom in the 80s with a boost from the MTV network. Three decades later, Idol still has the ageless heart and soul of a nonconformist teenage rebel.
