I was living in Abidjan for a period when Coupé Decale exploded in 2002-03, parallel to the ruthless Civil war when these guys were still teenagers. The violence between them was actually much worse then because there was ethnic violence between DJs from different regions and religions.
Regular shootings on Rue Princesse (the nightlife district) and young DJs being murdered. Arafat's first hit "Hommage à DJ Jonathan" was originally meant to be just a hommage to be played at his fallen friend's funeral, but it went international. People in their circles would kill guys over women, clothes, cars, you name it.
They adapted Congolese names and rapping in French/Lingala because ithey were neutral languages
Arafat seems to have matured past this level and worries for his life, the younger Debordo has not. How many times have they made up and fought again? Even Koffi tried to make them reconcile like school children on stage
