Miami bass

Miami bass (also known as booty music or booty bass, a term that may also include other genres, such as dirty rap), is a type of hip hop music that became popular in the 1980s and 1990s. The use of the Roland TR-808 sustained kick drum, raised dance tempos, and occasional sexually explicit lyrical content differentiate it from other hip hop subgenres. Music author Richie Unterberger has characterized Miami bass as using rhythms with a "stop start flavor" and "hissy" cymbals with lyrics that "reflected the language of the streets, particularly Miami's black ghettos such as Liberty City and Overtown".[1] Miami bass has never found consistent mainstream acceptance, though it has had a profound impact on the development of drum and bass, Baltimore Club, Southern rap, Funk carioca, and other genres.
