OK Jazz, later renamed TPOK Jazz (short for Tout Puissant Orchestre Kinois de Jazz), was a Congolese rumba band from the Democratic Republic of the Congo established in 1956 and fronted by Franco. The group disbanded in 1993, but reformed in 1996. Location The OK Jazz band was formed in 1956 in Léopoldville (now Kinshasa), in what was at the time the Belgian Congo (now the Democratic Republic of the Congo). At one time in the late 1970s and early 1980s the band grew to more than fifty members. During that period, it often split into two groups; one group stayed in Kinshasa, playing in nightclubs there, while the other group toured in Africa, Europe and North America. History 1950–1959 The musicians who started OK Jazz included Vicky Longomba, Jean Serge Essous, François Luambo Makiadi, De La Lune, Augustin Moniania Roitelet, La Monta LiBerlin, Saturnin Pandi, Nicolas Bosuma Bakili Dessoin and vocalist Philippe Lando Rossignol. They used to play at Loningisa Studios in Kinshasa as individual artists, before they got together to form a band in June 1956. The name OK Jazz originated from the bar where they played, which was called the OK Bar, owned by Gaston Cassien (who later changed his name to Oscar Kashama, after Authenticité). The new band played regularly at a specific studio in the city during the week, and on some weekends they played at weddings. In 1957, the lead vocalist, Philippe Lando Rossignol, quit OK Jazz and was replaced by Edo Nganga, from Congo-Brazzaville. Later in the same year, Isaac Musekiwa, a saxophonist from Zimbabwe, joined the band. Up to that time the band's leadership was shared between Vicky Longomba, Essous and Franco. 1960–1969 In the early 1960s Vicky Longomba and Jean Essous left OK Jazz to join African Jazz. Franco then became the leader of the band. He recruited vocalists Kwamy Munsi and Mulamba Joseph Mujos. Simaro Masiya Lutumba joined OK Jazz in 1961. Essous was replaced by saxophonist Verckys Kiamuangana Mateta. In 1962 OK Jazz visited Nigeria on their first foreign tour. Later that year, Vicky Longomba rejoined the band. Lola Checain, a vocalist who had left earlier also came back. Around this time, the band changed their name to TPOK Jazz. TP stood for "Tout Puissant" (all mighty). Band membership had increased to over twenty. The quality of their music had improved to where they could challenge African Jazz for
