In 1974, Akendengué recorded his first album, Nandipo, which consisted of songs of his own composition, sung in French and Nkomi, accompanied by guitar, women choir, bass and the percussion of Nana Vasconcelos. He later set to music poems by P. E. Mondjegou, such as "Le Chant du Coupeur d'Okoumé" ("The Song of the Okoumé Cutter"). Returning to Gabon, he studied solfeggio and plainchant at a Catholic college, and presented spectacles showcasing traditional Gabonese forms in a concert setting. In 1986, he received a doctorate from the University of Paris for his study of religion and education among the Nkomi.
