Update: Bizarre confirms D12 album in the works for 2014. Source
[Eminem]’s still the homeboy, I just saw him in the studio a couple of weeks ago […] Yeah, the group is still together, D12 is always gonna be attached to my name. I’m a founding member of D12, it’s not a game, it’s something that’s a life commitment. And we are definitely in the process of talking about recording a new album, getting the guys all together. Kuniva is doing a solo project, Swifty is doing stuff, but it’s coming soon. It’ll definitely be a new D12 album coming [in] 2014.
Eminem has reportedly been in the studio working with the Detroit hip-hop group D12. The four-member group never really was able to move past the tragic death of fifth member Proof and hasn’t released an album since 2004’s D12 World.
A recent article in the Detroit Free Press says quote:
[Mark] Bass, who has started a label called Motunes Media, says he’s also been mixing new material by the mercurial funk-pop giant Sly Stone with members of the original Family Stone band, along with new D12 tracks, including three with Eminem.
