It's a long story. But in short it was a leadership-war between Regis Touba and Quentin Moyascko. Durrel Loemba, Pinochet Thierry and Cyrrile Malonga who were all admins, siding with Regis Touba because they didn't like the way Quetin Moyascko decisions and trying to control everything. In order to show them who's the real boss, Quetin Moyascko manipulated the musicians and went with them to Europe without informing Durrel Loemba, Regis Touba and co. Them being confused when they saw the musicians having interviews in Europe to talk about their arrival. This all made Regis Touba, Durrel Loemba and co team up and form Z1 International. The funny thing is that they all prepared Merci together in Brazzaville. Many cries done by Etats Unis are creations of Regis Touba.
Yvan Angonga voice's is almost the same like legend Franklin Boukaka.
The second atalaku is TGV. But he does not convince. They had to let Etats Unis do animations on his own or bring another alataku on his placeI prefer Extra Musica International. I didn't really like Z1 International. They play like those gospel bands of the early 2000s (Thomas Lokofe, Rene Lokua and Mbuta Kamoka) that tried to do Ndombolo. That's why I said that Quetin Moyascko did good to get rid of Durrel Loemba and Cyrille Malonga. Otherwise Merci would have been like Super Helico. Ere de Verite had good songs, but I didn't like those unnecessary "changement de frequence" in their sebenes and that distortion-guitar. I think that distortion has to be forbidden for Clan Extra and just have to leave it to Zaiko and Quartier Latin. Durrel Loemba had good sebenes, but he never really convinced me as lead-guitarist. I don't see him as a natural solist. He had just to stay a rhythm-player and give his creations to other guitarists.
