"One Love," one of the most touching and imaginative songs on Illmatic, was the first song Q-Tip produced outside of A Tribe Called Quest — another sign of just how hyped Nas was before his debut. Tip later produced classics for Mobb Deep, the Crooklyn Dodgers and Janet Jackson before leaving Tribe and launching his sporadic solo career. Though he'd long toured the world as a DJ, his acclaimed 2008 album The Renaissance launched him back into the spotlight as an artist. He worked with Kanye West on My Beautiful Dark Twisted Fantasy and Watch the Throne before signing a deal with the superstar's imprint earlier this month. He's currently working on The Last Zulu, his G.O.O.D. Music debut, slated for release later this year.
