More Tyme, also known as Bx and Jim Siizer, is a Ugandan musical duo that performs under a record label called Lot Fire Records, an independent record label which nurtures new talents in Uganda, East Africa. The main singers of the group are Bx (born Ben Sserwadda) and Jim Siizer (born Nsobya James). Bx brings smooth RnB vocals, while Jim Siizer combines reggae and dancehall vibes in his performance.

Before embarking on their musical journey as a dynamic duo, Bx and Jim Siizer first crossed paths at Plan B Records, a recording studio in Mubende. It was there that they developed a strong friendship under the guidance of Selecta Williams, a radio presenter on Mubende FM 106.0. The turning point in their lives came when they participated in a music competition and caught the attention of Lot Fire Records, an independent record label which nurtures new talents in Uganda, East Africa. In 2023, Bx and Jim Siizer officially joined forces with Lot Fire Records and made their mark on the Ugandan music scene with the release of their debut single, "Balage." With this milestone, Bx and Jim Siizer became the first male musical duo to emerge from Uganda.
