Florida Georgia Line, the country duo comprised of Brian Kelley and Tyler Hubbard, has become the country chart's darling since the single "Cruise" debuted in 2012. The members have become the poster boys of "bro-country," a country subgenre in which songs typically include references to attractive women, pickup trucks and cheap beer. The beverages probably won't be as inexpensive at the inaugural Windy City LakeShake at Northerly Island, but that won't stop thousands of fans from showing up for the group's headlining set on June 21. We spoke with Brian Kelley—the "Florida" in Florida Georgia Line—about the band's tour, his iPhone collection and, of course, Chicago-style hot dogs.  In just a few short years Florida Georgia Line has gone from touring with Luke Bryan and Taylor Swift to headlining a national tour. What's different about going out on your own? It’s all different. Everything comes down to you, everybody’s looking to you, all the time. It’s a big responsibility but it’s a dream come true for us to be headlining and taking the tour all around [the country]. [All the fans] seem to be showing up partying. We had more than 18,000 down in Florida the other night—it was crazy. It looks like it’s going to be a hell of a summer, and we are very, very, very thankful for the fans. In 2012, a remix of your single "Cruise" featuring Nelly climbed the charts and became a pop radio staple. What inspired you to collaborate with a rapper?  How are you going to say no to Nelly?! O
