Big Boi is teaming up with a group simply known as Phantogram, who Boi allegedly discovered on a pop-up ad. Interesting. The trio of Big Boi and Phantogram (Josh Carter and Sarah Barthel) is slated to release their debut project, an EP, entitled Big Grams. The track list is short, as expected with an EP, but it features two huge acts: Run the Jewels and Skrillex. Polarizing features, I know. But you’ll be giving this a shot once it drops on September 25th via Epic. Check out the track listing after the jump, folks.
