Def Poetry is one of the country's fastest rising performing-art forms, and recognizing the power of urban poetry on modern culture, rap impresario Russell Simmons teamed up with HBO to create Russell Simmons Presents Def Poetry.

Season four of the improvisational, uninhibited late-night series features the spoken words of the biggest and most stellar talent line-up like Kanye West (6 time Grammy Award-winner), Tracy Morgan (30 Rock) and Mike Epps(Host of Russell Simmons' Def Comedy Jam).

Each episode is hosted by the highly regarded hip hop artist and actor Mos Def (hit album Black on Both Sides).
