Jay-Z to perform on eve of inauguration

Rapper is one of Barack Obama's biggest celeb supporters

Jay-Z isn't performing at President-elect Barack Obama's inauguration, but he is planning to make a big splash on the eve of the event.

The rapper, one of Obama's biggest celebrity boosters, has announced that he's playing a concert in Washington on Jan. 19, the day before Obama officially drops "elect" from his title.

Jay-Z will perform for a crowd of less than 2,000 at the Warner Theatre.
