In addition to his solo career, Eminem was a member of the hip hop group D12. He is also known for his collaborations with fellow Detroit-based rapper Royce da 5'9"; the two are collectively known as Bad Meets Evil. After his debut album Infinite (1996) and the extended play Slim Shady EP (1997), Eminem signed with Dr. Dre's Aftermath Entertainment and subsequently achieved mainstream popularity in 1999 with The Slim Shady LP, which earned him his first Grammy Award for Best Rap Album.

They were followed by Encore in 2004, which was another commercial success, but faced criticism by fans and critics for its lacklustre quality.
