Last Friday, New England’s biggest Hip-Hop event of the Summer, Jam’n 94.5's Summer Jam, went down at the Xfinity Center in Mansfield, MA. This may have actually been one of their best line-ups to date, however. Gracing the crowd of nearly 20,000 were industry heavy-hitters Kendrick Lamar, YG, Juicy J and more, including the one and only Jennifer Lopez.
