I just checked a few of the songs on https://www.supraphonline.cz/album/50244-entre-deux-mondes (the 1999 album isn't on suprphon) there's some good beat but it's not very complex music-wise. I'll try to find the 1999 album and check it too.
Given the musical composition (stanza, vocals, etc.) I hesitate to call that rap.
It's different from say Baby or Djadja by Nakamura, she's often categorized in Afrobeat but I would absolutely group them together in their style: I don't know how to name it (French Fusion?), but I love it!
Check the 1999 eponymous album, full of bangers.
