Teenage backpack-rap revivalist hasn't slowed down one second since bubbling up to national attention about a year ago, and now he's got a new single called "Underground Airplay" that pairs him up with fellow underground rap journeymen Smoke DZA and Big K.R.I.T. It's a particular treat to hear K.R.I.T.'s Mississippi drawl over a stark New York-style beat, but all three guys come off. The song's video, from directors Coodie & Chike, is more or less an Ecko Unlimited commercial disguised to look like a grimy black-and-white rap video. Watch it below. The track will appear on Ecko Unlimited's forthcoming Underground Airplay mixtape.
