2010 street mix. Way before Cassidy blew up off of "I'm a Hustler," he was known throughout his native Philly, and the rest of the East Coast, as one of the best freestylers and battle emcees around. The Problem Is Back works as a reminder of those earlier accolades as Cassidy shows the fire that had so many people excited about him when he first burst onto the scene. A lot of people in Hip Hop have been calling for a return to lyricism. With The Problem is Back Cassidy is looking to provide those people with exactly what they're looking for.
