One of the highest acoustic quality Congolese albums for me. He only used session artists (Shiko, Nyboma, Caen, Ngouma etc.) for that album. 3615 code niawu was the go to guy for animation, but he tried to go solo at that point.
In this interview with JMK, after the album release and while recording the clips, he mentioned he planned to use his musicans (Royaume système) and record in Kin his next album Tenent de titre.
This was the day he shot the clip for Nul n'est parfait
Favorites from Bonheur for me are Assistant sociale and Vieux samy.
