I distinctly remember both flopping hard (all A2BM generiques for that matter) in DRC & CIV. To the point he was mocked and became insecure with the generique department. He subsequently cleaned house and recruited a bunch of new atalakous leading up to Power.
Meanwhile WMM was dominating popluar music with the Techno Malewa craze carrying into 2010.
Qui est Deriere Toi? & Générique Bokoko were also dominating the hit parades when I was in Kinshasa early that year. Also, Felix Wazekwa with "La chèvre de M. Seguin" and later "Vraie puissance", even though Koffi tried to sabatoge both.
I do love A2BM for it's great, now classic rhumbas. The Zenith Live is also one of the best live albums, though it was actually recorded during a private session.
