Los Corraleros De Majagual

Los Corraleros de Majagual is a Colombian music group from the Caribbean coast. The group, which has recorded songs in the cumbia, porro, vallenato, and other Latin genres, has received over 30 gold records.
The group began in 1961 when Calixto Ochoa and Alfredo Gutiérrez met with Antonio Fuentes Estrada, owner of the Discos Fuentes record label. The group proposed a project of folk music in a rural context based on the accordion and the guacharaca. Fuentes named the group Los Corraleros de Majagual.
Over the years, the size of the group expanded, and "many of Colombia's biggest cumbia stars earned their stripes" playing with the Corraleros. In its larger configurations, the band "featured plenty of brass and percussion and generous helpings of high-octane squeeze box."
