Samuel Ateba Mengue is a session percussionist who has participated in many recordings, but I think this is his only record. Along with diverse percussion, Ateba sings throughout this set of traditional dance songs. There is very little information about this musician, and I only deduce he is from Gabon, based on the personnel participating on the album. Chief among them are Pierre Akendengue and his frequent choral singer, in his early recordings, Marianne Ndjongue.
Yet the structure of songs and the important dual role of response vocals as both rhythm and chorus, so similar to Akendengue's music, suggests Gabon. If you have further information about Ateba or this music, or even the exact date this record was released, please enlighten us in the comments.
