Eric Tutsi left by himself, because he didn't like the way Cultura was operating like a second class band, since that he felt himself like a god. His last concert was the one in Matadi, back in those days, the route of Kinshasa to Matadi wasn't like that of today. If you would go out the car, your face and clothes would be covered with sand. This happened with Eric Tutsi, when they returned the decided to leave and settle in Brazzaville for a moment, where he had alot of fans and donors before joining College de Noble after a year to leave it again after a few months, to return back in 2004 again to Quartier Latin.It had nothing to do with Babia, because Babia himself didn't participate on Loi & Ultimatum. Ultimatum was record in 1996, in Kenya with 6 singers (Sam Tshintu, Babia Ndonga, Eric Tutsi, Willy Bula, Suzuki Luzubu and Modogo), but when Koffi arrived for the tour in Europe, he lost the recording-files when he wanted to mix the album. So they had to record the album again, but this time Willy Bula, Babia Ndonga and Eric Tutsi weren't there because they were left behind in Kinshasa. Which made Koffi record it with just 4 singers (Bouro Mpela, Sam Tshintu, Modogo Ambarambwa and Suzuki Luzubu), in the same tour they recorded also Loi, since that Koffi wanted to his solo album before the end of 1997. That explains Eric Tutsi absence in both albums. Eric Tutsi was left behind for the tour of 1997, because he succes of V12, Magie and the tour of 1997 in Europe, made him big headed and not showing up in rehearshals or coming very late, the same for Babia. Like Babia, Eric would start to use strong drugs and become addicted to it. When Quartier Latin came back, Eric Tutsi was still not changing his behaviour, getting often suspended and his drugproblems would become until that he started to his voice. Then when the 1998-tour came that had Olympia & Zenith, he decided to bring for the first time 6 singers. From the 8 main singers, Eric Tutsi was then the worst at that time, because him not being able anymore to sing well and for his Olympia-show, Koffi wanted singers who also knew how to dance, but Eric Tutsi didn't know how to dance, so it was already known that he would be left behind once again. On the 1998-trip, Koffi decided to bring Depitcho, Bouro Mpela, Sam Tshintu, Modogo Ambrambwa, Babia Ndonga and Mamale, leaving Suzuki and Eric Tutsi behind, which why Eric Tutsi didn't sing on Droit de Veto. Then when Babia snitched to Koffi about the Academia-project, Koffi called his mother and staffmembers to recruit musicians in Kinshasa and ordered to get Eric Tutsi and do a rehab with Eric Tutsi ending up by becoming 100% clean and coordinating the rehearshals in Kinshasa with Rocky Blanchard who was also left behind. With those 25 singers/dancers all ending up by performing at Stade des Martyrs with Koffi, when he returned from the tour.
You don't know Koffi well. Koffi doesn't joke with his music, because he see it as his job, since that back in 1982 wasn't able to find a proper job in Kinshasa after finishing his studies. That's also why he's always in the spotlights try to adapt everytime never watch to the past like Emeneya, who were giving the impression that in you a timemachine in life. Koffi is really serious with music compared to JB, Adolphe and Werra,etc. who often don't showup to rehearshal and spent times in the studio. If Quartier Latin was like Clan Wenge, then Babia, Willy Bula and Eric Tutsi would never been left behind. If Maison Mere was Quartier Latin, then someone like Kakol would have been removed from his role as 'chef d'orchestre' and been left behind for a tour, like the way Koffi did to Champion when Koffi saw that he was not doing his role as 'chef d'orchestre' well and killing his band. Quartier Latin, that has a long list of chef d'orchestre and minor mistake can make Koffi furious and give someone else the role. The one who really lasted long as chef d'orchestre is Beniko Popolipo, followed by Fally Ipupa who replaced Felly Tyson in 2003.
