International Orchestra Safari Sound
The band was founded by Tanzanian business man Hugo Kisima, who also owned another popular dansi band, the Orchestra Safari Sound. In 1985 he decided to disband Orchestra Safari Sound and create a new ensemble with talented musicians hired from major dansi bands such as Mlimani Park. Kisima chose singer Muhiddin Maalin Gurumo, guitarist Abel Balthazar, and singer-songwriter Hassani Bitchuka as the leaders of the new band.
In the 1980s IOSS and Mlimani Park dominated the dansi scene. This came to an end between 1987 and 1989 when Bitchuka and Maalim left. In the early 1990s a new entry in the band's personnel, guitarist Nguza Mbangu (formerly Orchestra Maquis Original) revitalized IOSS for a while; Mbangu established a new mtindo, rashikanda wasaa, and wrote a big hit song, Mageuzi. Despite this, Kisima decided to disband the band in 1992.
