Jason Aldean and Tim McGraw will be getting in on the "March Madness."  The country stars are on board for next month's concert event in Dallas in conjunction with the men's' college basketball championship series. 

Aldean will headline the first day of the festival on Friday, April 4th.  McGraw will perform the next day, before the first semifinal game.  The Killers are also on board for the event's second day, and will take the stage after the game. 

Bruce Springsteen and the E Street Band are the event's headliner.  The band will close out the March Madness Music Festival on Sunday, April 6th, following a set from fun. 

More performers are expected to be announced in the coming weeks.  The shows are free and open to the public on a first-come, first-served basis.
