[3][4] Born in the village of Foase, in the Atwima District of the Ashanti Region in Ghana, West Africa, he worked in various jobs in science and medical-related fields while maintaining his interest in music.

In 1957, when the former British colony of the Gold Coast became the independent country of Ghana, Koo Nimo first received national acclaim through the formation of the Addadam Agofomma ensemble.

Along with one or two guitars and vocals, the traditional Ashanti palm wine ensemble consists of traditional instruments of West Africa, including the apentemma and the donno, the frikyiwa (metal castanet), the prempensua (rhumba box), the ntorwa (hollow gourd rattle with beads or seeds woven around it on a net), and the nnawuta (consisting of two iron bells that provide the key rhythmic pattern) or dawuro (banana-shaped bell).

[5] In January 1992, at Columbia University, New York, USA, Andrew L. Kaye presented his dissertation entitled "Koo Nimo and his circle: A Ghanaian Musician in Ethnomusicological Perspective" and was awarded a Doctor of Philosophy degree for his work.

More recently he has been made an honorary life member of the International Association for the Study of Popular Music, along with such distinguished names as Professor J. H. K. Nketia and John Collins.
