Based on their respective releases, you might not take Harlem's ASAP Rocky and Brooklyn's Theophilus London for the type of guys who would end up working together. But here they are, rocking out in a studio to a new collaborative tune, "Big $pender," that sounds, well, really big. Production on the track was handled by up-and-comer DJ Carnage. You can watch a making-of video of the track above. Apparently it's set to appear on London's new project, Lovers Holiday II: Rose Island, which is "[c]oming $oon."
