D12 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.

Marshall Bruce Mathers III, known professionally as Eminem, is an American rapper. He is credited with popularizing hip hop in Middle America and is widely regarded as one of the greatest rappers of all time. His global success is considered to have broken racial barriers to the acceptance of white rappers in popular music. While much of his transgressive work during the late 1990s and early 2000s made him a controversial figure, he came to be a representation of popular angst of the American underclass and has been cited as an influence by and upon many artists working in various genres.
