Kanye West and Chief Keef are working on new music. The Chicago entertainers were recently spotted in the studio together with Interscope A&R Larry Jackson. A picture of the session, apparently taken by Glo Gang member King Dris, recently surfaced on Instagram along with the hash tag, Bang3. Sosa’s forthcoming mixtape Bang 3 is slated to hit the ‘Net, March 3. Hopefully, it will not raise the murder rate as the Chicago rapper recently boasted. Check out the cover art for the project, here.
