Calypso music
The first major stars of calypso started crossing over to new audiences worldwide in the late 1930s. Attila the Hun, Roaring Lion and Lord Invader were first, followed by Lord Kitchener, one of the longest-lasting calypso stars in history—he continued to release hit records until his death in 2000. 1944's "Rum and Coca-Cola" by the Andrews Sisters, a cover version of a Lord Invader song, became an American hit despite the song being a very critical commentary on the explosion of prostitution, inflation and other negative influences accompanying the American military bases in Trinidad at the time. Perhaps the most straightforward way to describe the focus of calypso is that it articulated itself as a form of protest against the authoritarian colonial culture which existed at the time.
Music of Jamaica
As in many Anglo-Caribbean Caribbean islands, the calypso music of Trinidad & Tobago has become part of the culture of Jamaica. Jamaica's own local music mento is often confused with calypso music. 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.
