I'm not sure I agree with the idea that rock itself is dead. But the sort of rock that Bon Jovi made probably is. You either need to go heavier than they ever did into proper hard rock (Alter Bridge, Shinedown) or metal (Metallica, Slipknot), or go full on pop (Harry Styles etc) . Whilst only Metallica really have the legacy of Bon Jovi in terms of the rock bands, they release new music that I'd argue is relevant in its own right, not because of who is baking making it.
