This Alabamian rapper had a head start due to signing with Eminem's re-energized Shady Records (about the same time as vets Slaughterhouse joined the, well, house). He's been dropping Southern-fried solo sets since 2005, and appeared on Missy Eilliot's UPN show "Road to Stardom" and was even signed to Columbia initially. But he finally got the push he needed with the release of 2009's excellent EP "Trunk Muzik 0-60" through Ghet-O-Vision/Interscope. This past fall, his full-length "Radioactive" had the aide of Shady himself producing, and stars like Kid Rock and T.I. guesting -- just imagine who he may hit the road with in 2012.
