bands had moved on and were replaced by the younger musicians. Bands such as Swinging Stars, The Gaylords, De Boys an Dem, Los Caballeros and Swinging Busters surfaced and began to cut records. The emergence of radio, first WIDBS and later Radio Dominica helped to spread the music. Calypso has been popular in Dominica since the 1950s; the first Calypso King was crowned in 1959. Popular calypso in Dominica has always been closely associated with steelpan music. The first wave of Dominican steelpan includes such bands as Esso, Shell and Regent, Vauxhall and Old Oak. Cadence (kadans)/compas In the 1970s, a wave of Haitian, mostly musicians, to Dominica and the French Antilles (Guadeloupe and Martinique) brought with them the kadans, a sophisticated form of music that quickly swept the island and helped unite all the former French colonies of the Caribbean by combining their cultural influences. This was followed by mini-jazz like Les Gentlemen, Les Leopards, Les Vikings de Guadeloupe and others. Later in the decade and into the 1980s, the French Antilles became home to a style of cadence music called cadence-lypso. Gordon Henderson's Exile One innovated this style, as well as turned the mini-jazz combos into guitar-dominated big bands with a full-horn section and the newly arrived synthesizers, paving the way for the success of large groups like Grammacks, Experience 7, among others. Drawing on these influences, the supergroup Kassav' invented zouk and popularized it with hit songs including "Zouk-La-Se Sel Medikaman Nou Ni". Kassav' formed in Paris in 1978. Cadence-lypso The most influential figure in the promotion of Cadence-lypso was the Dominican group Exile One (based on the island of Guadeloupe) that featured mostly the cadence rampa of Haiti and calypso music from the English-speaking Caribbean. It was pushed in the 1970s by groups from Dominica, and was the first style of Dominican music to find international acclaim. Dominica cadence music has evolved under the influence of Dominican and Caribbean/Latin rhythms, as well as rock and roll, soul, and funk music from the United States. By the end of the 1970s, Gordon Henderson defined Cadence-lypso as "a synthesis of Caribbean and African musical patterns fusing the traditional with the contemporary". Aside from Exile One, other bands included the Grammacks, Black Roots, Black Machine, Naked Feet, Belles Combo, Mantra, Black Affairs, Liquid Ice, Wafrikai, Midnighte Groovers and Milestone, while the most famous singers included Bill Thomas, Chubby Marc,
