D12 (also known as The Dirty Dozen) was an American hip hop collective. They were formed in 1996 by Eminem, Proof, Bizarre, D Ratt, B-Flat, Mr. Porter, and Eye Kyu in Detroit, Michigan.
The band gained significant notoriety thanks to Eminem's international success. Taking advantage of this success, they have managed to rank their albums at the top of sales in many countries, including the United States and the United Kingdom. Their best known singles were "Fight Music", "Purple Pills", "My Band", "Shit on You", and "How Come". Since 2006 after the death of Proof, the group has remained almost inactive because of Eminem's drug problems. It led to its withdrawal from the music scene for more than three years and the departure of Mr. Porter and Bizarre in 2012. However, the group reformed several times in 2014, only for Eminem to announce their breakup on "Stepping Stone" from Kamikaze.
