Guy Warren (born Kofi Ghanaba, 1923 in Acra) was a Ghanaian musician, best known as the inventer of Afro-jazz and a member of The Tempos. He began his professional career as a drummer in the [[Acro Rhythmic Orchestra before working with Kwame Nkrumah, a Ghanaian nationalist. He spent time in London, Liberia and Chicago, working in jazz but achieving little success, though he did work with such stars as Thelonius Monk and Charlie Parker. He was eventually hired by Decca, a record label trying to cash in on the exotica craze, but did not find an audience. In 1965, he returned to Ghana, studying Buddhism and teaching music to a few visitors.
