It became popular, because many Angolan Bakongo from Kinshasa hadn't next to Congolese and Angolan music, not really a song of their roots to dance about. Which forced them often to dance just the tribal songs of Bantandu, the northern Bakongo living next to Kinshasa (Kisantu, Kasangulu, Madimba). Some had it in possession, but they were very hard to find. Then when I think the cd of "Musique Folklorique de Bakongo de l'Angola refugies au Congo Kinshasa" came out the song "Matali Yo" and "Makonda Mbuta" it became massive hit. Major Bisadidi who has Angolan roots, promoted both songs in his movies, which made the song getting more succes. Later also Bangala, Baluba who like Bakongo-music started to put the music in their parties and wedding.
