The Roots have never had a problem bucking the status quo. Now, two years after The Tipping Point, they return with their angriest, most uncompromising album yet. On Game Theory the Philly hip-hop collective draws on angst both political (the war on terror) and personal (the death of close friend and collaborator J Dilla) to create an expertly-crafted and relentlessly funky depiction of our times. In anticipation of Game Theory's release, The Roots hit us with exclusive live performances of songs from the new album.
