Being Atlanta rap royalty is a tough job, but Big Boi knows someone's got to do it. The rapper, who obviously comprises one half of the legendary duo OutKast, has a new album out later this year – his first solo full-length for five years – and it includes a collab track with another of Southern hip hop's biggest and most enduring names, Run the Jewels' Killer Mike.Last night, ATL radio station V103 threw a pop-up concert in the city on Saturday, featuring a performance from Big Boi. Now, you don't get to the top of the pile in one of the rap capitals of the world without knowing how to put on a show, so it's only right that he brought out his collaborator to debut their new track, which features Big Boi spitting over a more contemporary, trap-inflected beat, obviously to the delight of the crowd.Watch the performance below, and keep your eyes peeled for more updates on the album (also if anyone knows where I can get a miniature version of Big Boi's all white ensemble then please get at me immediately):Follow Lauren on Twitter.(Image via Wikimedia Commons)
