B.o.B was fortunate enough to land Eminem as a guest on his debut album 'B.o.B Presents: The Adventures of Bobby Ray,' but now the ATL rapper will take it a step further when he opens for Em and Jay-Z at Detroit's Comerica Park on Sept. 2 and 3.

The shows are already being dubbed the "World Series of Hip-Hop." With the addition of Bobby Ray, Jay-Z will still open up for Eminem in his hometown, while the Detroit emcee will return the favor at the second set of concerts at Yankee stadium in New York the following weekend.
Each of the Detroit concerts is expected to pull in about 40,000 fans and the show's production director, Dan Parise, has revealed that the set will feature heavy video elements and special effects. Preparations for the concerts have been months in the making and Eminem recently revealed that fans should expect to hear some classic Slim Shady songs in addition to tracks from his latest album 'Recovery.' "I don't want to give anything away," Em told Billboard, explaining that he planned to cover a variety of material. It "will probably be all over the place," he said. "Hopefully it'll be songs that everyone is familiar with."
Additional tickets for the Detroit show went on sale early Wednesday morning, giving fans another chance to score seats. The duo will take their home-and-home concert set to Yankee Stadium in New York on Sept. 13 and 14.
