Bugz

D12 (an initialism for the Dirty Dozen) was an American hip hop collective from Detroit, Michigan.

Formed in 1996, the group achieved mainstream success with its lineup of de facto leader Eminem, Proof, Bizarre, Mr. Porter, Kuniva and Swifty McVay.

D12 was initially formed in 1996 by Proof who invited local Detroit rappers such as Bizarre, Da Brigade members Mr. Porter and Kuniva, and Bugz.

In 1997, they released their debut extended play, The Underground EP, which was recorded between 1996 and 1997.

Eminem and Eye-Kyu had guest appearances on it.

In 1997 and 1998, its members began establishing reputations locally.

Bizarre was named Inner City Entertainment's "Flava of the Week" and went on to release an EP, Attack of the Weirdos.

Along with Eminem, he became an honorary member of the Outsidaz.

Proof won a freestyling competition run by The Source.

In 1999, Bugz released These Streets EP, and made several appearances on other rappers' songs.

On May 21, 1999, Bugz was shot and killed.

One of his final acts had been a request that Swifty McVay join the group.

Eminem volunteered to replace Bugz; this led to him joining the group.

D12 had chart-topping albums in the United States, United Kingdom, and Australia during the early 2000s.

The group released the albums Devil's Night in 2001 and D12 World in 2004, spawning numerous hits such as "Shit on You", "Purple Pills", "Fight Music", "My Band" and "How Come" throughout that period.

Both albums were certified double platinum by the Recording Industry Association of America (RIAA).

Their debut album, Devil's Night, referring to the tradition of setting unoccupied buildings on fire the night before Halloween, was released in June 2001.

It debuted at number one on the U.S. and number two on the UK chart, also reaching the top of the Canadian charts.

The album went on to sell four million albums worldwide and two million in the U.S.

In 2004, the group won the MTV Europe Music Award for Best Hip-Hop Act.

D12 World was released on April 27, 2004, featuring production by Eminem, Mr. Porter, Dr. Dre and Kanye West, and guest appearances by Obie Trice on the track "Loyalty" and B-Real of Cypress Hill on the track "American Psycho II".

It debuted at the top of the U.S., UK, and Australian albums charts, and at number two in Germany—selling over half a million records in its first week of release in the U.S. alone.

"My Band", the album's first single, also reached number one in Australia, New Zealand and the U.S. rhythmic top forty, the top five in the UK and Germany, and the top ten on the Billboard Hot 100.

In 2005, Bizarre and Proof released their debut studio albums Hannicap Circus and Searching for Jerry Garcia.

They debuted at numbers 48 and 65 on the U.S., respectively.

Since 2006, Eminem's hiatus and the death of Proof resulted in the group being less active in subsequent years.

On April 11, 2006, Proof "pistol-whipped an unarmed man and shot him in the head", and was in turn fatally shot by the man's cousin.

On December 5, 2006, Shady Records released Eminem Presents: The Re-Up which featured performances by Eminem, 50 Cent, Obie Trice, Stat Quo, Bobby Creekwater and Cashis while affiliated artists such as Lloyd Banks, Akon and Nate Dogg, made guest appearances.

Some tracks were collaborative performances from D12 members, such as "Murder" by Bizarre and Kuniva and "Whatever You Want" by Swifty McVay and Mr. Porter.

The track "Trapped" by Proof included an intro by Eminem paying his final respects saying, "Big Proof, rest in peace dudey we love you. We just wanna keep making you proud."

Between 2008 and 2015, D12 released three official mixtapes with the core lineup reduced to Bizarre, Kuniva and Swifty McVay, with isolated token appearances by Eminem and some contributions from Mr. Porter and Fuzz Scoota.

On May 21, 2008, D12 released their first mixtape Return of the Dozen Vol. 1.

In 2010, the group recorded "Hit Me with Your Best Shot" for Eminem's scrapped seventh studio album Relapse 2.

Since then, Eminem was no longer a member of the group, having guest appearances only on two tracks, "Fame" on Return of the Dozen Vol. 2 (2011) and "Devil's Night Intro" on The Devil's Night Mixtape (2015).

The mixtape Return of the Dozen Vol. 2 (2011) followed three years later.

It featured Fuzz Scoota, a new member of the group.

On August 5, 2011, D12 performed at the Kanrocksas Music Festival.

In 2012, Bizarre and Mr. Porter left the group.

In January 2014, Mark Bass of the Bass Brothers confirmed that D12 had been recently recording at the F.B.T. studio and he had been mixing their recorded material.

On August 31, 2018, Eminem released his tenth studio album Kamikaze, containing a song titled "Stepping Stone", announcing that D12 had officially disbanded.
