Hip-hop history was made as Jay-Z and Eminem co-headlined the Motor City’s Comerica Park on Thursday night (September 2), the first of two shows on consecutive nights.

While Jay’s high-grossing touring schedule helped him to top this year’s Forbes’ “Hip-Hop Cash King” list, Eminem took a much-needed sabbatical to deal with plenty of personal issues. Now beyond his darkest hour, Em had one of his brightest moments ever onstage. Not only did he gift his hometown with a seemingly endless string of hits, he pulled off some major surprises. After D12, 50 Cent and the G-Unit — acts that fans likely expected — came out for performances with Em, Slim Shady pulled off a shocker. Dr. Dre came out, first stunning the people then delighting them with smashes.

Other special guest appearanced included Jeezy, Drake and many more… Checkout Vid after the jump.
