I wonder what Maison Mere, BCBG and Quartier Latin made not going there anymore. Back in 70, 80 & early 90s would have those counter-shows, for example when Isifi Lokole performed after their birth, Zaiko Langa Langa immediately hit back the next week. Or in the late 80s, Zaiko Familia Dei giving their first show and the next week Zaiko Nkolo Mboka performing and presenting their new musicians.
It would have created polemic, if Wenge BCBG immediatly performed the week after it, but they went the same week to Europe and also didn't perform when coming back from Europe.
