Since he released his 2009 album Sleep Therapy, Milwaukee rapper JC Poppe has established himself as the city's most prominent hip-hop blogger, charting the local scene at his blog Milwaukee UP, while promoting and managing local rap acts on the side.

Yesterday Poppe debuted his video for the Shadowlands single "Foundation of a Movement," a state-of-rap treatise with a chilled-out, DJ Premier-esque beat by Danny Diggs and scratches from DJ Mayhem.
