Before Tupac, before Notorious B.I.G., before Jay-Z or Lil Wayne, there was Chuck D! In the mid '80s, Chuck D and his group, Public Enemy, signed with the rap label Def Jam. You know, that bedroom record label that discovered little groups like the Beastie Boys, LL Cool J and some thrash metal band named Slayer. Ring a bell? With Def Jam's support and Chuck D at the helm, Public Enemy championed socially conscious rap music in America. With politically charged albums like It Takes A Nation Of Millions To Hold Us Back and Fear of a Black Planet (the latter selling 1 million copies week of release), Public Enemy remains one of the most important rap groups in history.
