Gumbe Music Festival Bissau in Bissau
Gumbe is Guinea-Bissau's signature polyrhythmic music genre, built on Crioulo call-and-response vocals and dated to around 1973, with Manecas Costa its best-known international performer. A standalone annual festival under this exact name is not clearly documented, though gumbe is widely heard during carnival and at local concerts in Bissau.
Gumbe is the name most closely associated with Guinea-Bissau's own musical identity, a polyrhythmic style that fuses roughly ten of the country's folk music traditions into a single genre built on call-and-response vocals sung in Crioulo, the Portuguese-based Creole spoken across the country.
