While a new OutKast album may not be in the works, Big Boi continues his solo grind with his #MashUpMondays series. For the sixth installment, Daddy Fat Sacks enlists synth-pop duo Phantogram for “Objectum Shalamar,” which comes with its own trippy visuals.

You can catch Big and André 3000 at over 40 festivals this summer including Coachella, Governors Ball, and OVO Fest.
