Eminem goes old-school for his upcoming LP

Eminem is stepping back in time for his new LP, joining forces with a rapper he hasn't collaborated with in over a decade.

Detroit-based Royce Da 5'9" worked with Eminem back in '99 on his debut album, The Slim Shady LP.

The pair’s believed to have kept their distance from each other over the years after having a feud of some sort.

Luckily, the situation changed in January when the rapper’s group Slaughterhouse signed to Eminem's label.

"Royce and I started hanging out again and inevitably that led us back into the studio," Eminem told MTV UK.

"At first we were just seeing where it went without any real goal in mind, but the songs started to come together crazy, so here we are."

Royce said he was stoked to be working with Em again.

"I'm excited to see this project come to fruition considering the long lapse in time between when we worked before and now. We had a blast doing it and we just hope everyone enjoys it while we're working on the monster that will be the Slaughterhouse album."
