When Jay-Z graced the stage at the Glastonbury Festival in 2008, he was holding a guitar—a response to Oasis leader Noel Gallagher's comments criticizing Jay as a headliner of the traditionally rock-based show.
Jay wasn't the first, nor the last, rapper to play a guitar. (Although, he doesn't really know how to play.) Lil Wayne dropped rock album Rebirth in 2010 and he was seen everywhere with a guitar. Kid Cudi did the same, releasing an alternative project two years later. Then there are the rarely seen, incredibly awesome pictures of MCs like Nas and 2Pac rocking out.
