La Sonora Dinamita is a Colombian cumbia group. As one of the first cumbia groups to reach international success, it is credited with helping to popularize the genre throughout Latin America. The original orchestra was formed in 1960 in Cartagena de Indias under the direction of bandleader Lucho Argaín. It disbanded in 1963, but was re-formed in 1975 under the direction of Julio Ernesto Estrada "Fruko" Rincón, the artistic director of the Discos Fuentes record label. In 1981, Mélida Yará, better-known as "La India Meliyará" became the lead vocalist.
