Lil Wayne w/ Rick Ross, Keri Hilson, Far East Movement and Lloyd

Self-proclaimed “greatest rapper alive” Lil Wayne didn't waste any time returning to his breakneck schedule following his release from prison last year; he's recorded dozens of guest verses and has reportedly finished Tha Carter IV, the long-delayed sequel to his 2008 blockbuster Tha Carter III, the best-selling album of that year. To tide fans over, last month he released a feisty mixtape titled Sorry 4 the Wait. Sharing this tour with Wayne is fellow radio mainstay Rick Ross. After being outed in 2008 as a former correctional officer—a revelation that would have almost instantly killed the credibility and careers of most mid-level gangsta rappers—the stout Florida rapper silenced critics with his great 2009 record, Deeper Than Rap. His 2010 follow-up, Teflon Don, was even better, a hard-hitting but also immensely soulful rap album featuring assists from a host of modern R&B greats, including John Legend, Cee Lo, Erykah Badu, Ne-Yo and Raphael Saadiq.
