Nteregu is a visual and sonic journey through the music of Guinea-Bissau. From the rhythms of the Tina (traditional Guinean drum) and the communal spirit of the “mandjuandadi,” to the “tabancas” of the “griots” and the dance floors of Europe, the film traces the evolution of Guinean music across centuries. Featuring ancestral instruments and rare testimonies, it shows how music serves as a bridge, passing down values and knowledge between generations. The film also highlights how women, through the Tina, laid the cultural foundation of the nation and helped unify diverse ethnic groups through music.
