Big Boi took to Instagram this week to announce that his joint album with Phantogram is complete.

An electronic duo known for their ethereal soundscapes and funky beats, Phantogram appeared on three songs on Big Boi' 2012 album Vicious Lies And Dangerous Rumors -- "Objectum Sexuality," "CPU" and "Lines" feat. A$AP Rocky. 

Collectively, Big Boi & Phantogram go by the moniker Big Grams. They announced the joint album in April 2014, when Big Boi described the logistics of their collaboration: “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.” 

Run the Jewels will appear on one of the tracks, and this pic suggest a Kendrick appearance could be in the cards. Stay tuned for more news regarding this very promising album.
