Guy Nsangue played like Djudjuchet on all songs of the album (except the sebene-parts), but maybe tbat he even played on some sebenes. Because Didier Masela was often coming late during studio session and sometimes not even showing up. They for example recorded Likama on the last minute. That's why Japonais played bass on some songs, but it can be that they erased all those parts he played, to let them correct by Guy Nsangue.
Yeah, its a shame that Christian stayed. He was one of the best bassists of his generation.
