D12 member Kuniva shared some insight into the group’s recording process on Twitter, explaining how Eminem would let members know that their verses had been removed from a track. The group was primarily comprised of Kuniva, Em, Bizarre, Mr. Porter, Swifty McVay and Proof. When a member didn’t deliver with their verse, Em would break the news to them in the studio using a move Kuniva dubbed “The Kneel.”

Kuniva later tweeted that he got “The Kneel” on “American Psycho” off the group’s debut LP Devil’s Night. The song ultimately included verses from Em, Bizarre, and Mr. Porter.

Eminem was the leader of D12 and produced much of their music. The group poked fun at the dynamic between members and the others' relative obscurity compared to Em on “My Band,” their biggest hit.

On “Stepping Stone” from his 2018 album Kamikaze, Eminem rapped about the rise and fall of D12, taking accountability for not doing enough to support the other MCs and declaring the group finished. He raps:

Feels like I’m on the descent, but it was not my intent

To treat y'all like a stepping stone

Though I ain’t left no one behind, but we been down every road

Done all we possibly can, I know we kept our hopes up

But the longer we spend livin' this lie that we live

The less is left for closure, so let’s let this go

It’s not goodbye to our friendship, but D12 is over

D12’s last release was The Devil’s Night Mixtape in 2015, while Kuniva recently released the Royce da 5’9” and Kid Vishis collaboration “Keep Calm.”
