What could be better than New York's own Jay-Z playing the first concert at the new Yankee Stadium?

How about fellow rap superstar Eminem alongside him?

The two titans of the hip-hop world attended Wednesday night's New York-Detroit game at Comerica Park to announce they'd be playing at the Yankees' ballpark on Sept. 13.

On Sept. 2, though, Jay-Z will be back in the Motor City to play with Eminem at the latter's hometown ballpark, Comerica Park.

They made the announcement during appearances on several television broadcasts of Wednesday night's game. The concerts will be produced by Live Nation.

Jay-Z, whose recent New York-centric anthem, "Empire State of Mind," was a a big hit, performed the song before Game 2 of the World Series at Yankee Stadium.
