Superstar rappers Eminem and Jay-Z will play a Comerica Park show in September, the Free Press has learned.
The late-summer blockbuster is part of a two-show stand that will include a date at New York's Yankee Stadium -- a home-and-home series for Detroit's Eminem and New York's Jay-Z.
The two will announce the dates during the third inning of tonight's game between the Detroit Tigers and New York Yankees at Comerica Park, to be aired on ESPN. They warmed up for the appearance at about 6 p.m. today, wearing their respective teams' ball caps and posing with Tigers players on the Comerica field.
It’s as star-powered a match-up as they come: Eminem and Jay-Z, two of the top-selling music acts of the past decade, were ranked No. 1 and 2 respectively in Vibe magazine's Best Rapper Alive poll in 2008.
Ticket on-sale information is not yet available.
