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 history of the United States in the 1970s
Popular music of the United States in the 1970s saw various forms of pop music dominating the charts. Often characterized as being shallow, 1970s pop took many forms and could be seen as a reaction against the high-energy and activist pop of the previous decade. It began with singer-songwriters like Carole King and Carly Simon topping the charts, while New York City saw a period of great innovation; hip hop, punk rock and salsa were invented in 1970s New York, which was also a center for electronic music, techno and disco.
