UGK, short for Underground Kingz, were at the pinnacle of their craft, the highest point of their career. They had made songs with the biggest of rap stars and gained an international following unparalleled by other Houston MCs. But it all came crashing down in December when Pimp C suddenly died. The 2007 double CD Underground Kingz received raves and will serve as their opus, no matter if it was meant to or not. Five years from now, there'll be no reunion album. There will be no "Steel Wheels" tour down the road. There will only be the quality music the duo released over the years.
