I don't know about the history of the group. But few of them were already based in Paris. Olivier Kalabasi for example used to live in Ngaba and sended when he was a kid to Europe, because his parents cou;dn't handle him. He had to live with I think his brother, who was already living in Europe. But later on started to do music and played in Jeunes Premiers and Les Heritier before joining Anti Volcan. Mike Diapason who playing in the video was also already based in Paris (he could be borh there), his dad used to be guitarist in Paris.
