Documented career positions
Rajab Abdul Kahali, known professionally as Harmonize or "Konde Boy," is a Tanzanian Bongo Flava superstar and the founder of Konde Music Worldwide. Discovered by Diamond Platnumz, Harmonize was the first major artist signed to WCB Wasafi, rocketing to fame with hits like "Bado" and "Kwangwaru." He built a massive fan base by blending Makonde cultural elements with mainstream Afrobeats. In 2019, Harmonize made a deeply controversial and highly publicized exit from WCB Wasafi, paying a massive buyout clause (reported to be over Ksh 22 million) to gain his independence. He immediately launched Konde Music Worldwide (KondeGang), successfully establishing himself as a standalone powerhouse. He is heavily involved in political mobilization, frequently releasing praise songs for national leaders, including the late President Magufuli and President Samia Suluhu Hassan.
