It’s been a while since a radio freestyle got this heavy. But you know— the UK likes to do it big. On MistaJam’s BBC Radio 1Xtra show, it was history in the booth as UK heavyweights Dizzee Rascal, Skepta, JME, Footsie, Jammer, Fekky, Lethal Bizzle, Tempa T, and General Levy all stepped to the mic for the first time ever together. The video starts with Lethal Bizzle’s “Rari Workout” with JME and Tempa T providing the verses, then launches into plenty of freestyle craziness. And don’t worry, those phones ain’t out to read bars, they’re just recording the madness. Watch the footage in the player above or catch the video for “Rari Workout” below.
