Midwest hip-hop is hip hop music performed by artists from the Midwestern United States. In contrast with its East Coast, West Coast and Southern counterparts, Midwest hip hop has very few constants in style or production. Midwest hip hop's first dose of national popularity came in the mid-90s with the extremely fast-paced rappers known as Choppers, such as Bone Thugs-n-Harmony (Cleveland), Twista (Chicago), Tech N9ne (Kansas City), Atmosphere (Minneapolis), and Eminem (Detroit). However, while the artists mentioned above became the first to introduce Midwest hip hop that rivaled the popularity of West and East Coast styles, subsequent acts have since risen to national prominence such as Nelly, D12, Common, Chief Keef, Kanye West, Kid Cudi, Big Sean, and Chance the Rapper but they share very few similarities. Other notable midwest rappers and producers include: Brother Ali, Lupe Fiasco, Royce Da 5'9, J Dilla, Mac Lethal, Elzhi, Obie Trice, and up and comers Freddie Gibbs and Manny Phesto. It is because these lack of constants between acts from different cities (and sometimes even between artists from the same city) that it can be extremely difficult to define a "typical" Midwest sound. One characteristic of Midwest hip hop is that beat tempos can range from 90 to about 180, while East Coast's beat tempo is 90–120, West Coast is 100–120, and Southern rap is 80–180.
