Call Marty McFly, because ProbCause and Gramatik just went straight Back To The Future with us. What an interesting combo we have here. Rapper, ProbCause teams up with funky producer, Gramatik to give us their newest single, “Back To The Future.” This funky future-hop track is just what you need to get you through this week. The Chicago based rapper flows perfectly over the funky jam we have come to expect from Gramatik. Stay tuned for ProbCause’s album coming out on August 28th.
