Los Bambacoa were an Argentine musical group, pioneers of cumbia in the 1960s. Their distinctive sound blended vocals with clarinets and trombones, creating an unmistakable style. The ensemble included Álvarez on timbal, Tetamanti on güiro, Rubén Di Génova on congas, Carlos López Caldi, Ricardo Salinas on piano, Osvaldo Bertolini on bass, Hugo Rodríguez Fazio, Julio Napolitano, and Martino on clarinets, Cacho Gorostiaga on rallador and vocals, and the late Rolo Quinteros as the lead singer. In 1965, they released their sole LP under RCA, featuring hits like "Arena y plata" and "Cantando por el río." Their success led them to perform extensively across Argentina and abroad, appearing on television programs such as "Escala musical" and participating in events like the Fiesta Provincial del Trigo. In 1966, they appeared in the film "Ritmo, amor y juventud," performing "Dengue de Colores." The group disbanded in the late 1960s.
