Jay-Z will play another free concert to rally support for U.S. presidential candidate Barack Obama in the run up to the election.

Hova has already backed Obama's White House campaign by playing a free gig in Detroit, Michigan earlier this month.

The event will be hosted by basketball star LeBron James.
