Isifi
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), Shungu Wembadio (Papa Wemba), along with Evoloko Lay Lay, Mavuela Somo and Bozi Boziana (who'd joined Zaiko Langa Langa a year earlier), left Zaiko Langa Langa to establish their own musical ensemble Isifi Lokole, ISIFI being an acronym for "Institut du Savoir Ideologique pour la Formation des Idoles." Yet of course, not everything that Wemba claims in earnest can be taken as gospel. In July 1975, Shungu Wembadio officially adopted the soon-to-be-well-known worldwide artist name Papa Wemba, the addition of "Papa" (father) an allusion to what were in fact rather awesome family responsibilities as the first son in a family where both father and mother (Wemba's parents) had been deceased since the 1960s.
The "feux d'artifice" (fireworks) that was Isifi Lokole would only last a year, with the single "Amazone" (Papa Wemba) as its biggest commercial "hit" record. In November 1975, Papa Wemba, Mavuela Somo and Bozi Boziana abandoned Evoloko Lay Lay and Isifi Lokole to create the group Yoka Lokole (also known as The Kinshasa's Wa Fania All-Stars, or Lokole Isifi, or simply Isifi), along with Mbuta Mashakado, another Zaiko Langa Langa 'transfusion.' Yoka Lokole enjoyed slightly less popular success than the original Isifi Lokole, but for a time still managed to remain at the top the African pop music wave with hit songs like "Matembele Bangui", "Lisuma ya Zazu" (Papa Wemba), "Mavuela Sala Keba", and "Bana Kin" (Mavuela Somo).
Like Isifi Lokole, the electronic-instrument driven Yoka Lokole (or The Kinshasa All-Stars) would not last much longer than a year, given the merger of so many big-name talents in the band's lineup. After a year of modest success, controversies within Yoka Lokole over money and prestige (complicated by Wemba's arrest and brief incarceration in Kinshasa Central prison in December 1976 for the 'crime' of being suspected of having had physical intimacy with an influential army general's daughter) would lead Papa Wemba, then feeling diminished by peers and neglected by the public, to form his own group Viva la Musica in February 1977 after a very brief return to Isifi Lokole and Stukas Boys of Lita Bembo where he played for a few weeks as a guest.
