Jonas Mosa Gwangwa OIG (19 October 1937 – 23 January 2021) was a South African jazz musician, songwriter and producer.
In the 1960s, he began to gain notice in the United States, and in 1965 he was featured in a "Sound Of Africa" concert at Carnegie Hall.
Initially exiled to the United States, Gwangwa spent the late 1970s and a better part of the 1980s living in Gaborone, Botswana, where he founded the band Shakawe that included South African musicians Steve Dyer, Dennis Mpale, Tony Cedras and local Botswana musicians Rampholo Molefhe, Whyte Kgopo, Bonjo Keipedile, Tsholofelo Giddie and Japie Phiri.
During his time in Gaborone, Gwangwa got involved in the MEDU Art Ensemble, a collection of anti-apartheid musicians, visual artists, and writers, working alongside other Botswana-based South African exiles such as Keorapetse Kgositsile, Baleka Mbeta, Tim Williams, Thami Mnyele and Mongane Wally Serote.
During the June 14, 1985 apartheid South African Defence Force cross border Raid on Gaborone, which killed MEDU members Mnyele, Mike Hamlyn and ten others, as well as bombing a house recently vacated by MEDU leader Williams, Gwangwa believed he and other artistic exiles were being targeted by the apartheid government and returned to overseas exile.
