Mento

Wikipedia - "Mento is a style of Jamaican folk music that predates and has greatly influenced ska and reggae music. Mento typically features acoustic instruments, such as acoustic guitar, banjo, hand drums, and the rhumba box — a large mbira in the shape of a box that can be sat on while played. The rhumba box carries the bass part of the music. Mento is often confused with calypso, a musical form from Trinidad and Tobago. Although the two share many similarities, they are separate and distinct musical forms. During the mid-20th century, mento was conflated with calypso, and mento was frequently referred to as calypso, kalypso and mento calypso; mento singers frequently used calypso songs and techniques. As in Calypso, Mento uses topical lyrics with a humorous slant, commenting on poverty and other social issues. Sexual innuendos are also common."
