also vying for an audience with other (at the time) new musical acts such as Bella-Bella and Empire Bakuba. Isifi Lokole In December 1974, at the pinnacle of their fame (and just a month after the Rumble in the Jungle between Muhammad Ali and George Foreman in Kinshasa), Papa Wemba (usually called 'Shungu Wembadio' at this point in his career) along with Evoloko Lay Lay, Mavuela Somo and Bozi Boziana, left Zaiko Langa Langa to establish their own musical ensemble Isifi Lokole. Wemba later claimed that ISIFI was an acronym for "Institut du Savoir Ideologique pour la Formation des Idoles," a claim that has still not been given total credence. In July 1975, Shungu Wembadio officially adopted the soon-to-be-well-known-worldwide name Papa Wemba. The "Papa" (father) part of his name had already been given to him as a traditional and cultural rite because he was his mother's first-born son. But in assuming a new name and public persona, "Papa" was now re-emphasized as an allusion to the demanding family responsibilities that Wemba assumed at very young age, since both parents were now deceased: Wemba's father in 1966, followed by his mother in 1973. Isifi Lokole would only last a year together as a group, with the single "Amazone" (a Wemba composition) as its biggest commercial "hit" record. Yoka Lokole In November 1975, Papa Wemba, Mavuela Somo and Bozi Boziana left Isifi Lokole to create the group Yoka Lokole (also known as The Kinshasa's Wa Fania All-Stars). Yoka Lokole contributed to the African pop music wave with their hit songs including "Matembele Bangui", "Lisuma ya Zazu" (Papa Wemba), "Mavuela Sala Keba", and "Bana Kin" (Mavuela Somo). Like Isifi Lokole, the electronic-instrument-driven Yoka Lokole would not last much longer than a year. After a year of modest success, controversies within Yoka Lokole over money and prestige were also complicated by Wemba's arrest and brief incarceration in Kinshasa Central prison in December 1976 when he was suspected of having a relationship with army general's daughter. The band continued to tour without Papa Wemba. For whatever reason (or reasons), whether it was personal or professional (with one source speculating that he was perhaps feeling diminished in the public's eye), by 1977 Wemba had formed a new group, and called it Viva la Musica. Viva la Musica In 1977–78, back home now in the Matonge neighborhood of Kinshasa, Papa Wemba set out to create his group
