to national prominence by finding artists like La Sonora Dinamita, who brought cumbia to Mexico, where it remains popular. It is worth pointing out that the "classic" cumbia known throughout Colombia is the Cumbia Cienaguera. This song reflects a uniquely Colombian feel known as "sabor" (flavour) and "ambiente" (atmosphere). Arguably, this song has remained a Colombian staple through the years and is widely known as Colombia's unofficial national anthem. Some artists are Los Gaiteros de San Jacinto, Los Graduados, Los Black Stars, Los Golden Boys, Los Teen Agers, and Los Corraleros de Majagual. In the United States, an Afro- Colombian band based in New York called Grupo Rebolu, performs a variety of Afro-Colombian rhythms with authentic instruments such as Tambora and Tambor Alegre. Their repertoire includes Cumbia and many more genres from the Northern coast of Colombia as part of their original compositions. Champeta and African-diasporic music Some Colombian communities, such as Chocó, Cartagena, San Andres and Providence Island, have large African-descendant communities. Unlike most of the country, cultural mixing with native and European influences have been rare, and, especially in El Chocó, music has changed little since being imported from West Africa. Providencia Island is also home to a type of folk music which is closely related to mento, a Jamaican folk form. Most influentially, however, is the city of Cartagena and its champeta music which has been influenced by soukous, compas, zouk, and reggae. Champeta musicians have included Luis Towers, El Afinaíto, El Sayayín, El Pupy, and Boogaloo, while others like Elio Boom have incorporated Jamaican raggamuffin music to champeta. Porro Porro bands are a form of big band music that came from Sucre, Córdoba and Sabana de Bolívar. The brass ensembles are modeled after European military bands. Notable porros include Pacho Galan. Eastern Caribbean musical region Vallenato Vallenato was first played by the pre-Columbian Indians using traditional instruments. The first vallenato singer was Guillermo Buitrago, born in the Magdalena department. Vallenato did not always use accordion as its main instrument. In fact, from 1920 to 1936 the main instrument was the guitar. Groups such as bovea and sus vallenatos also are among the first vallenato singers. They form the group in the city of Barranquilla Atlantico department. They also were the first to take the vallenato music to a different country like Argentina, specifically in northern Argentina. Contrary to popular belief, vallenato is not a rhythm. Rather,
