After wrapping up a headlining tour to mark the 20th anniversary of OutKast, Andre 3000 appears to be making progress on his long-rumored new solo album.

As Consequence of Sound points out, in a photo shared by comedian Chris Rock, it appears as if Andre 3000 is collaborating with Jack White, A Tribe Called Quest’s Jarobi White and producer D-Nice, who has worked with the likes of KRS-One and Kid Rock, among others.

Both Andre 3000 and White have disappeared from the public eye after very busy touring years in 2014 and 2015. Both OutKast and White headlined many of the same festivals over the course of the summer with White on his Lazaretto tour and Andre teaming once again with Big Boi on OutKast’s reunion tour.
