It is sad the core of this group in this Album went to QL Wazekwa could have become an heavyweight if everybody stayed, Eclipse is good but Gessac gave that something more. Even though I have never understood why he was trying to copy Bill when singing he had a beautiful natural voice that you can hear when he forget to copy Bill, I think he would have been respected more if he just stayed original, because he had talent, he brought Wazekwa to another level, and I can understand Koffi offered a lot of money and number one spot right away but if you compare Eclipse lifestyle and Gessac of course Eclipse lives better so maybe going to QL was a huge mistake. Nono Chaka had some melancholy on his voice like a nostalgic out of time voice it is sad he never have the chance to fully express his potential.
About the rhumba section I don't know much of the name but it is one of the few choirs in Congolese music where everything is balanced and the sound is so clean
