Zubz' "Victory" and Tumi's "Music From My Good Eye" both had the same beat by Mizi.
In 2006, revered South African lyricists Zubz and Tumi (now known as Stogie T) released the albums Headphone Music in a Parallel World and Music From My Good Eye. On both albums, the opening songs ("Victory" by Zubz and "Music From My Good Eye" by Tumi and Fifi The RaiBlaster), both rappers used the same beat from Pretoria producer Mizi, who also produced most of Headphone Music.
It's been known for a long time that both Zubz and Tumi had no idea they were given the same beat until they had recorded the songs. They only went back to shout each other's names after hearing the songs.
Mizi recently shared how he got to give both MCs the same instrumental in a must-listen interview on Massiv Metro. Instro, another veteran SA hip-hop producer, invited his counterparts to his show Producers Paradise. "I know that Zubz used some live instruments, but essentially it's the same beat," said Instro about the instrumental.
