Rombongan Bodonk Koplo, Ncum is an Indonesian musical ensemble associated with the dangdut koplo subgenre, a contemporary, rhythmically intensified form of dangdut that emerged in Java. The name suggests a regional performance group specializing in bodonk koplo, a style characterized by heavy, syncopated drum patterns, electronic keyboard ornamentation, and tempos suited to dance; such ensembles typically perform at local events and record informal albums or videos. Activity for groups of this type is primarily within Indonesia’s popular music scene from the late 20th century into the 21st century, with an emphasis on energetic live performance, crowd interaction, and reinterpretation of well-known dangdut repertoire.
