The industry isn't making any new rock stars. Name one band that has debuted in the last 7 years that can headline an arena by themselves and a single opening act. You can't, there aren't any.
Not sure when they got their start (and I'll forego any comment on their music):
Mumford & Sons
Breaking Benjamin
One Direction
Black Keys
Now if you want to include pop stars, not just rock, then the list is huge.
