Unfinished Business is the second collaboration LP between Jay-Z and R. Kelly (following The Best of Both Worlds, their first collaboration in 2002), released in 2004. The album was, allegedly, composed of previously unreleased tracks from the Best of Both Worlds sessions. It was seen by critics and the general public as just a money making opportunity for both artists and a play to push a summer tour.

The first single was "Big Chips".
