During Andre 3000’s hiatus, Big Boi collaborated with electro rock duo, Phantogram. Backstage at Coachella, he tells the Hollywood Reporter that they have an album’s worth of music.

Meanwhile, Big Boi is also working on a full collaborative release with New York band Phantogram, titled Big Grams. At present, the release is an EP, but Big Boi is open to it becoming a larger, full-length effort. Either way, it likely won’t emerge until after the rapper’s next solo album. “We’ve got songs which were already recorded when we were working on my last record,” he said. “They come down to Stankonia and we camp out for like a week and trade vibes. They go back to New York, then they come back down and we just keep the process going.”
