The internet has changed a lot about music, especially in hip-hop. With barriers to entry broken down, the regional nature of music isn’t as prevalent. Yes, rappers still rep their city, but a lot of the new guys come up on the internet with just as many fans in New York as Los Angeles. It’s not necessary to put on hundreds of shows in your hometown in order to build a solid following.
The regional rapper still exists though, and when you start with one city and work your way up from there, it almost always goes well. The internet is a fickle beast, but get your city on your back and you’re on your way. Just look at 2 Chainz and Atlanta. Right now, King Louie is that dude in Chicago, and “Too Cool” just keeps going. First the remix, now the video. Next he just needs to make a second song as good as this one.
