Faustin Mangituka Ntaminimo (born 7 July 1962), known professionally as Bébé Atalaku, is a Congolese songwriter and musician whose work with Nono Monzuluku has significantly shaped Congolese music, mainly through his role as an atalaku in Zaïko Langa Langa.

Both siblings were members of the folkloric group Bana Odéon, which was based in the Kintambo commune and included Nono Monzuluku and percussionist Djerba Manzeku.

His entry into the band initiated the introduction of the atalaku role in the Congolese rumba section called sebene, a role he pioneered with Nono Monzuluku, who had joined Zaïko Langa Langa shortly before him.

[3][4] Atalaku, performers who sing and shout during dance segments in sebene to inspire and energize audience to dance, gained immense popularity across Africa, with nearly every band incorporating atalaku in their music.

[3][5][6] Bébé toured Africa, Europe, the Americas, and Asia as part of Zaïko Langa Langa and contributed to several of the band's well-known albums, including Nippon Banzai (1986), Pusa Kuna… Serrez!
