International Orchestra Safari Sound (sometimes shortened to IOSS) was a popular muziki wa dansi Tanzanian band from 1985 to 1992.
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.
The major mtindo (style) popularized by IOSS was ndekule, a word that is both a reference to traditional Tanzanian war dances and to a species of snakes.
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.
