Sierra Leonean palm wine music is known as maringa, and it was first popularized by Ebenezer Calender & His Maringar Band, who used styles that came from freed slaves from the Caribbean, especially Trinidadiancalypso. Calendar's most popular song was "Double-Decker Bus".
Bissaun gumbe music was popular in Sierra Leone, and has led to a unique offshoot called milo-jazz.
In the 1980s, SE Rogie became the most prominent Sierra Leonean musician, playing to large audiences across Europe and North America.
