Senegalese hip hop began to emerge in the early 1980s.
 When hip hop first hit the scene in Africa, it went from merely being a fad, to a more social and political movement.
 Amongst the most influential leaders of this movement were artists from the country of Senegal.
 With the modernization of the country, and the rise in media, the youth of Senegal were able to embrace a new form of expression.
 One of the main reasons why hip hop has become preeminent in Senegal is due to its mixture of sound and culture.
 "Senegal's hip hop scene is distinctive and its artist extremely talented.
 The country has a history of strong musical traditions..." Moreover, hip hop has not only become an aspect of life for the Senegalese people, but more importantly has translated to a way of life, gathering influence from the musical expression prior to its rise in Senegal, and understanding their past as it pertains heavily to its socially present state within music.

Cubans or Cuban people (Spanish: "Cubanos" ) are the inhabitants or citizens of Cuba.
 Cuba is a multi-ethnic nation, home to people of different ethnic and national backgrounds.
 As a result, some Cubans do not treat their nationality as an ethnicity but as a citizenship with various ethnicities and national origins comprising the "Cuban people."
 The majority of Cubans descend from Spaniards.
 Despite its multi-ethnic composition, the culture held in common by most Cubans is referred to as mainstream Cuban culture, a Western culture largely derived from the traditions of Western European migrants, beginning with the early Spanish settlers, along with other Europeans arriving later but in much smaller numbers, such as the English, French and Italians.
 There is a West African cultural component which has been somewhat influential, with many Afro-Cubans also being of Haitian or other Afro-Caribbean origin.

 Since the 1920s Jazz Age, jazz has become recognized as a major form of musical expression.
 It then emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation.
 Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation.
 Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music.
 Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience and styles to the art form as well.
 Intellectuals around the world have hailed jazz as "one of America's original art forms".
