Yesterday we shared the news that Big Boi of OutKast will be joining Phantogram, a duo he discovered via a pop-up ad. The trio, known simply as Big Grams, will be dropping an EP on September 25th via Epic. It’ll feature Run the Jewels and Skrillex. And today they’re sharing “Fell in the Sun,” the first teaser from the project. It’s a fine number; there’s a funky backdrop with thick drums, and Big Boi rapping like Pimp C, kinda. The hook, sung by Sarah Barthel of Phantogram, is serviceable, but is ultimately missing a lil’ something extra to put it over for a win. Overall, this is a decent first showing from Big Grams. But, we’re all patiently waiting the arrival of the Run the Jewels cut, which should happen any day now. Peep “Fell in the Sun” after the jump.
