Zex Bilangilangi real names Mayega Tadeo grew up in a slum in Kamwokya, a slum in Kampala, Uganda. He is an artist, businessman & an activist. He started making serious music when he was 17. He wanted to use his talent to make the ghettos a better place.

Soon, Zex started working with a lot of charities. That's when he met Ghetto President Bobi Wine at a talent search that Bobi Wine had set up. After that, Zex joined Bobi Wine's Fire Base Crew, a music label known for edutainment, positive and inspiring music, and arts in general. Zex is a high-ranking member of the crew, and Bobi Wine called him "ghetto prime minister."

Since then, Zex has become a role model for young people in Uganda, especially those who live in poor ghettos.
