Cam'ron and Just Blaze shut down the Broccoli Music Festival in Washington D.C. this past weekend. Cam already had the crowd vibing, but then took it to the next level when Just Blaze joined him on stage to perform the Roc-A-Fella hits, "I Really Mean It" and "Oh Boy." Luckily the cameras were rolling and caught footage of the occasion, which you can view above.
