Good Question! ID a problem. Provide a solution
And this is problem that's been around forever! Haven't we all grown up in the most boring place in ever?
Here's my idea. It seems that all the talent shows, like American Idol, America's Got Talent, You Think You can Dance, are super popular right now. How about provide a smaller venue like those, for the local teens? Kinda like a comedy club for teens -- but with different type events: singing, dancing, talent show, etc.
Whenever I go to the mall on weekends, it seems like that there is always a band or a singer performing on the public stages. Make sure you provide a voting device for audiences, so that they can participate.
