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.
Salsa music
Salsa emerged from New York City in the mid-1970s, then spread throughout Latin America and the Western Hemisphere. However, the music had already been going strong in the city for several decades prior to the use of the label "salsa". New York had been a center of Cuban-style dance music since the 1940s, when landmark innovations by Machito's Afro-Cubans helped usher in the mambo era. Tito Puente worked for a time in the Afro-Cubans before starting up his own successful band. By the early 1950s, there were three very popular mambo big bands in New York: Machito and his Afro-Cubans, Tito Puente, and Tito Rodríguez. There were many other working bands as well. The Palladium Ballroom was the epicenter of mambo in New York. At the height of its popularity, the Palladium attracted Hollywood and Broadway stars, especially on Wednesday nights, when a free dance lesson was offered. The mambo and its "temple", the Palladium, were racially and ethnically integrated phenomena.
