Killer track from Orchestre Poly-Rythmo De Cotonou. The studio version can be found on an Analog Africa compilation,
Skeletal Essences Of Afro Funk – 1969 to 1980. Other albums from this group still in-print include
Cotonou Club,
Vodoun Effect – Funk & Sato From Benin's Obscure Labels 1973 to 1975 and
Echos Hypnotiques. Songs will overlap but I'd recommend starting off with the Skeletal Essences cd.
