This summer, Big Boi told his Twitter followers that he was to appear on the two Andre-assisted songs but ultimately didn't because "'Dre didn't want an OutKast Record Coming out on anybody else LP."
The duo seem to have had a change of heart. In August, Big Boi told Billboard "an OutKast feature on a project that's not mine or his is not what we wanted to do right now."
On Dec. 29, Big Boi posted a photo on Tumblr of his upcoming verse for the "channel ORANGE" track. "Dropping a verse on this Frank Ocean 'Pink Matter' #vladr," he wrote.
Big Boi will also lay a verse on Tip's "Sorry," which features Andre 3000 apologizing about events in OutKast's past. "I'm sorry, I'm awkward / My fault for fucking up the tours / I hated all the attention so I ran from it / Fuck it if we did, but I hope we didn't' lose any fans from it,'" 3 Stacks raps. Check out the "Trouble Man" track above.
