EDM and 4th of July fireworks. It seems like a marriage made in Heaven—if Heaven were a Las Vegas casino. Afrojack, the DJ that has more money than he knows what to do with (according to The New Yorker), brings huge beats and a bunch of sky explosives to 6000+ people on the eastern tip of Navy Pier. After producing a string of hits for Pitbull, the Dutch house kingpin is finally getting around to his own debut album, Forget the World, which features Snoop Dogg and Sting. It's the rare all-ages EDM event, and it'll be pretty bonkers. Ravers: you can Build-A-Bear beforehand.
