Mac Miller

Starting as a little-known rapper using social networking to connect with his fans, Mac Miller is the perfect example of what YouTube views, Facebook likes and Twitter followers can do for a career. Now, with a huge fan base, sold-out concerts and the support of some of hip hop's most-revered emcees, the cool suburban kid who once shook up the underground is flooding the mainstream. After being recognized by XXL as one of hip hop's most promising newcomers, Miller's year got even better when his debut album, Blue Slide Park, hit number one on Billboard 200.
