WCB newest signee Mbosso, whose government names are Mbwana Yusuph Kilungi is the true definition of the saying that states, "hard work pays".

The "Nadekezwa" hitmaker kicked off his singing career with the popular boy-band Yamoto Band where he sang along Aslay, Beka Flavour, and Enock Bella.

When Yamoto Band was disbanded, he went back home and continued being a farmer until when the WCB Wasafi record artist Rayvanny followed up on him and brought him back to Dar es Salaam where he later signed with Wasafi.

The singer has managed to rise up the ranks of the most successful bongo stars and is currently known for hits such Watakubali, Nadekezwa, Hodari, Alele, and Nimekuzoea.
