Mighty Sparrow
Calypso music enjoyed a brief period of popularity in other parts in the world during the 1950s. Trinidadian expatriate Lord Kitchener had helped popularize calypso in England, and Sparrow also found some success there. In the United States, interest in calypso was sparked largely by Harry Belafonte's 1956 album "Calypso", the first LP to sell over one million copies. In January 1958, Sparrow, along with longtime rival Lord Melody, travelled to New York City seeking access to the American music audience. Sparrow had already been recording with Balisier and Cook Records, and with Belafonte's help he also began to record for RCA Victor. He did not achieve the success he had hoped for; he said in a 2001 interview, "When nothing happened for me, I went back to England and continued on with my career."
Monica Boyar
During the 1939 New York World's Fair she made a concerted effort to persuade Americans to adopt the Dominican Republic's native dance, the merengue. An initial reluctance eventually subsided, and by 1955 it was the fastest growing dance in the U.S. When Boyar introduced calypso songs to America, many felt the music was not commercial. By 1954 calypso songs were among the bestsellers.
