He is a reggae singer, songwriter, producer, promoter and has organised multiple concerts through his Jazz Safari brand.
Tshaka was born in 1972 to Ruth Nkangi and Jehoash Mayanja Nkangi, the former Buganda Kingdom prime minister and Uganda cabinet minister
Mayanja grew up in Kyambogo and went to Nakasero Primary School for one year, before joining Budo Junior School where he completed P.7.
Tshaka Mayanja started playing musical instruments while in school and the first instrument he learnt to play was the piano.
He went to King's College Budo for O-Level and Makerere College School for A-Level.
He started organising concerts while in high school.
After A-Level, he refused to join university and instead convinced his parents to pursue a certificate in computer studies.
In high school, at Budo, using drums, they would create beats with his friends.
Growing up in a family that loved music helped him nurture his career. Dad was a great dancer and mum was also involved in music as a singer.
He, however, never saw himself becoming a musician, as he was initially interested mostly in football.
In 2019, he revealed that, except for one event held in 1996, he had never made money from organising events.
The founder and director of Jazz Safari over the years flew into the country big names like Chaka Demus and Pliers, Buju Banton, Shaba Ranks, Hugh Masekela, Jonathan Butler and many more.
