Concertgoers declared last night’s Eminem and Jay-Z Home And Home Motor City kick-off date the best show ever, while MTV News noted, “Detroit hasn’t screamed this loud at a baseball park since Kirk Gibson was hitting home runs in the 1984 World Series.” It was a night that saw Marshall Mathers stage a triumphant hometown gig at Comerica Park that boasted guests like Dr. Dre, 50 Cent, D12, Drake and Trick Trick, plus a “Magic”-al opening set from B.o.B.

During the evening, 50 Cent stepped on the stage with Em for “Patiently Waiting,” while Drake returned a favor to Em—who recently showed up for the Toronto rapper’s own OVO Festival hometown gig—by joining him for “Forever.”

But by far, the night’s biggest surprise was Dr. Dre, who MTV says walked on stage “first stunning the people then delighting them with smashes.”

And Billboard reports the following about Em’s mentor Andre Young:

“The stadium shook when Dr. Dre came on stage for ‘Still Dre’ and ‘Nuthin’ But a ‘G’ Thang,’ with Eminem taking up Snoop Dogg’s parts. When Eminem led the crowd in chanting for Dre’s long-awaited Detox album, the producer—who sported a Proof T-shirt – promised, ‘I’m comin’!’ Curiously, neither he nor 50 Cent were part of ‘Crack a Bottle,’ even though they appear on the recording and were obviously in the house.”

Dre’s Detox is supposedly due out sometime this year.

Here’s Slim asking Detroit to “make some muthafuckin’ noise” for Dre last night. The crowd responded by chanting “Detox, Detox, Detox!”

Hova’s set followed Em’s. The pair will perform again tonight at Comerica Park before heading to Jay’s “home” of New York and  doing a two-night stint at Yankee Stadium beginning September 13.
