It's well established that Redman is one of Eminem's favorite rappers, so it's really no surprise that Slim decided to call into Shade 45 when Redman was in studio last night. Hearing Em and Redman go back and forth was a really cool moment, especially as they traded stories and about the old days, and showed mutual love for one another.

One interesting added tidbit during the call was that Eminem revealed he was currently hard at work on some new music. This comes as a bit of a surprise, since Slim has not announced anything official about a new album. His last project, Shady XV, was a compilation and greatest hits project, so it's basically been over two years since Eminem has dropped a real solo album.

Is something coming from Marshall Mathers in the future? Looks like we'll have to wait and see. One thing is for sure though, Em said he's in for a feature on Redman's Muddy Waters 2 album. Listen to Slim and Redman's full conversation below.
