Although it may not feel like it yet, summer is just around the corner with its unforgiving heat waves. But there is at least one person that won’t be phased when the temperatures reach triple digits. That person is Just Juice. On the DJBooth premiere of his new single, Coolin, the 19-year-old Boston emcee raps like a veteran from the South over the soulful production stylings of C-Sick. The ease he shows when switching up flows mid sentence shows control beyond his age. Whether it’s stepping to the devil on the last dance or hotboxing the drop top, Just Juice knows how to maintain his cool. The unsigned artist hasn’t yet placed Coolin on a larger body of work, but you can enjoy his last Booth feature, Driven, until he does.
