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.
Rapso
Rapso is a form of Trinidadian music that grew out of the social unrest of the 1970s. Black Power and unions grew in the 1970s, and rapso grew along with them. The first recording was "Blow Away" by Lancelot Layne in 1970. Six years later, Cheryl Byron (founder of the New York City based Something Positive Dance Company) was scorned when she sang rapso at a calypso tent; she is now called the "Mother of Rapso".
