A talented recording engineer friend of mine has recently returned from Ghana, where he recorded Gospel choirs in and around Accra, as well as the last session before the passing of late brilliant Ghanaian jazz drummer, Kofi Ghanaba (also known as Guy Warren). He was noted for his musical works with Charlie Parker, Thelonius Monk, and original Ghanaian highlife band The Tempos. Generally, his work transferred through jazz drumset, Afro, free music, from and back into traditional drums and beyond.

BAPMAF, an NGO archival collection, standing for Bokoor African Popular Music Archives Foundation. It is maintained by Professor John Collins, author, musician and ethnomusicologist, at the University of Ghana. The archives pay attention to the history of Ghanaian highlife music and its performers.
Koo Nimo, aka Daniel Amponsah, the original celebrated beautiful Palm wine guitarist. Palm wine guitar, which he made popular in the 1960s, uses a form of plucking akin to classical and flamenco guitar used in popular song. His is some of the most beautiful music I've ever heard. Koo brought Palmwine guitar from the Asante region (middle-west) of Ghana.
