The chantwell became a calypsonian in the 1920s and calypso became widely popular throughout Trinidad and the Caribbean in the 1930s. Harry Belafonte, a Jamaican-born artist, became hugely successful throughout the world with his 1956 "Calypso" becoming a million seller. During the 1960s, calypso was merged with Indian music and later soul and funk to become soca.
Mento
Due in part to Belafonte's popularity, mento became widely conflated with calypso in the 1950s. In a 1957 interview for "Calypso Star" magazine, Lord Flea explained:
"In Jamaica, we call our music 'mento' until very recently. Today, 'calypso' is beginning to be used for all kinds of West Indian music. This is because it's become so commercialized there. Some people like to think of West Indians as carefree natives who work and sing and play and laugh their lives away. But this isn't so. Most of the people there are hard working folks, and many of them are smart business men. If the tourists want "calypso", that's what we sell them." 
This was the golden age of mento, as records pressed by Stanley Motta, Ivan Chin, Ken Khouri and others brought the music to a new audience. In the 1960s it became overshadowed by ska and reggae. Mento is still played in Jamaica, especially in areas frequented by tourists. Lloyd Bradley, reggae historian and author of the seminal reggae book, "Bass Culture," said that Lee "Scratch" Perry’s seminal 1976 dub album, "Super Ape," contained some of the purest mento influences he knew. This style of music was revived in popularity by the Jolly Boys in the late 1980s and early 1990s with the release of four recordings on First Warning Records/Rykodisc and a tour that included the United States. Stanley Beckford and Gilzene and the Blue Light Mento Band also revived rural mento in the 2000s. The mento dance is a Jamaican folk-form dance with acoustic guitar, banjo, hand drums and rhumba box.
