The Rail Band is a Malian band formed in 1970; it was later known as Super Rail Band, Bamako Rail Band or, most comprehensively and formally, Super Rail Band of the Buffet Hotel de la Gare, Bamako.
 Its fame was built upon the mid-20th century craze for Latin — especially Cuban — jazz music which came out of Congo in the 1940s.
 The Rail Band was one of the first West African acts to combine this mature Afro-Latin sound with traditional instruments and styles.
 In their case, this was built upon the Mande Griot praise singer tradition, along with Bambara and other Malian and Guinean musical traditions.
 Their distinctive sound came from combining electric guitar and jazz horns with soaring Mandinka and Bamabara lyrical lines, African and western drums, and local instruments such as the kora and the Balafon.
 At their height of fame in the 1970s, the Rail Band played to sold out venues and even stadia across West Africa, and launched solo careers for many of its members, including the legendary vocalist Salif Keita.
Guimba the Tyrant (French: "Guimba, un tyran, une époque" ) is a 1995 Malian comedy drama film in the Bambara language (with some Fula language components), directed by noted Malian director Cheick Oumar Sissoko.
 The movie shows the rise and fall of a cruel and despotic village chief "Guimba", and his son "Jangine" in a fictional village in the Sahel of Mali.
 Some of the storytelling was done through the medium of the village griot, and with the film being placed in an old setting, lends an epic touch to the movie.
 The exact chronological setting of the movie is difficult to ascertain, being set in an isolated village, but the commonly used weaponry shown is the blunderbuss (however one scene outside the village features a neem tree, a species introduced to Africa during the colonial period).
 The film depicts some magical components, including a solar eclipse brought on by magic.
 Casting was only partially done from among professional actors.

 The Manding languages were spoken in the empire.
 It was the largest empire in West Africa and profoundly influenced the culture of West Africa through the spread of its language, laws and customs.
 Much of the recorded information about the Mali Empire comes from 14th century North African Arab historian Ibn Khaldun, 14th century Moroccan traveller Ibn Battuta and 16th century Moroccan traveller Leo Africanus.
