I researched Congolese music a little bit and found out that during WWII a great deal of musical fusion, particularly with Latin styles, occurred in much of Africa. This music was often called "soukous" which is a derivative of the French word "secousse" which means to shake. Soukous is also sometimes referred to as African Rumba. The Congolese music scene was vibrant in the 60s and 70s, with the soukous' tempos being sped up and more influenced by rock n roll over time.
Many musicians migrated to other countries, or left for Paris in the 70s as the political conditions deteriorated. Since the 1990s, Congolese popular music has declined significantly. The president at the time (Mobutu) repressed indigenous music, and Paris became a major center for Congolese music.
Does anyone know of any contemporary Congolese music I should check out???
