With their latest, "OC," Lil Durk and labelmate OTF Nunu are two for two on great 2014 collaborations (see their triumphant "At The Top" from earlier this year). Nunu's quickly becoming the most promising non-Durk member of their OTF crew, particularly in the wake of RondoNumbaNine's arrest. The lurching "OC," named for the Chicago slang for "out of control," will likely appear both on Durk's Signed To The Streets 2 and Nunu's debut mixtape, Nuski Got Da Strap.
