I am not exactly sure of the release date, but somewhere in April 2001, Felix Wazekwa released the album Signature. It was his fifth solo album, following Tetragramme, Pauvre Mais, Bonjour Monsieur and Sponsor. This album made him finally breakthrough on the Congolese music scene. The générique and the dance Male ma Mbwa were huge success. The success of the générique made him get nominaed as “Best Central African Male Artist” at the Kora Awards, where he did a play-show with a few members of the Cultura Pays-Vie
Because of Wazekwa's reputation as being one of Koffi’s former ghostwriters, several journalists in 2001 started ask Koffi Olomidé about Felix Wazekwa, often making him visibly uncomfortable. In Signature, Wazekwa threw different shots at Koffi Olomidé, saying for example "Zacharie Bababaswe, baloba pembeni na micro te" (Zacharie Bababaswe, they do not have to talk next to the mic). As reference to one interview Koffi once did with Zacharie Bababaswe back in 1999 or 1998, where he was asked about Felix Wazekwa, but Koffi ignoring him on tv, only to acknowledge him behind the camera after the interview. In the song Bilan du Travail from Koffi's album Effrakata, Koffi said "Zacharie Bababaswe, soki ozo bunda na ntaba, kobanga mino naye te". (Zacharie Bababaswe, if you are fighting with a goat, don't be afraid of his teeth). The public believe that it was an attack to Wazekwa, being compared to a goat due to his beard.
Although the album being a huge success, the majority of those who participated in it had left the group, as they stayed in Europe. Only the atalaku Gessac and Papy Louange, singer Joss Diena and guitarists Hono Kapanga and Bijoux de Polga remained in the group. Singer Tripason who had an important role in the album would start a career as session-singer and participate to a huge number of albums till the mid-2000s. While drummer Freddy Telecel would back the band Pesa Munu Passage of gospel-singer Mbuta Kamoka, where he would perform at Zenith de Paris in October 2001.
The success of the album grew even more when Eric Tutsi and CNN from Quartier Latin joined the band.
Felix Wazekwa ended up by getting voted as 3rd Best Star of the year 2001 by ACMCO, behind Adolphe Dominguez, who finished 2nd and JB Mpiana and Werrason, who shared the number one spot. The same Adolphe Dominguez was guest on Felix Wazekwa's Signature, where they had a conversation in the song Ah Bon. The song Ah Bon was a follow up on the first part of Ah Bon from the Sponsor album, which was a conversation between Djuna Djanana (father of Maitre Gims) and Felix Wazekwa, where on the end of the song Wazekwa said that the head of village asked to people invited to the party “What he could do while he was alive that would make people stop talking about him after his death?”. In a few interviews after the release of Sponsor journalists were wondering about his answer to it. In the conversation between Adolphe Dominguez and Felix Wazkekwa promised people in the song that he would respond, but instead of it he would just come with shout-outs, Adolphe Dominguez as well andtalking about his departure from Maison Mère, saying that he suffered alot and was insulted and beated up. Also mentioned how Blaise Bula sheered him up by saying that he did well by leaving as he was in Werrason's shadow and that everyone as his own band (Masela, him, Adolphe, Werrason and JB) and Makaba soon also creating his own band.
The album Signature had also a song called Heros du Siècle, where Bitou Djeny "le Karmapa" would sing for the first time in the studio, doing a vocal with Joss Diena towards the end. Joss Diena once revealed that all singers were against Karmapa doing vocal. Karmapa would after Signature contact late Jean Pierre Saah to do an album on his label sending a demo of a few songs. But he was rejected which hurt him a lot and when asking to influent donors of Matete, to support him financially with his project to record an album, they all refused saying that they were focused on Felix Wazekwa. Until one day, he teamed up with Eric Lukasi and Werrason, who was in conflict with Felix Wazekwa, looking someone who could challenge him and Karmapa having the best profile, since he came from Eurppe like Wazekwa and also used to be a ghostwriter of Papa Wemba. Werrason wanting Karmapa to name his name "Nani apesi yo permission ?" (Who give you the permission). But Karmapa refusing the album-title as it would create alot of polemic and just throw alot of shots towards Wazekwa in the album. Eric Lukasi then producing Karmapa's first album Je m'Appelle Toi ? where former Cultura-singer Tripason would participate as one of the vocalists.
The rivalry between Koffi Olomidé and Félix Wazekwa took another dimension in 2002, when Koffi and Quartier Latin were not allowed to perform in Wazekwa’s area, Matete, at Somi Somida’s venue. Kuluna's blocked Quartier Latin from performing. The incident created a lot of controversy, with Wazekwa and his team bragging in the media, saying that each group should stay in its own goalpost similar to how Vita fans and Imana fans each have their own sections in Stade de 20 Mai.
Due to the success of Signature, Wazekwa received a contract to perform in July 2002 at LSC, bringing Cultura Pays-Vie to Europe to do the show and record the at that time upcoming album Yo Nani?
