Zachi is a member of 01099 (pronounced "zero-ten-ninety-nine"), a German rap crew from Dresden. The crew name refers to the zip code of Dresden-Neustadt (01099), the rappers' place of origin.
The four musicians Dani, Gustav, Paul and Zachi got to know each other partly as orchestral musicians, but mostly as young children in the sandpit and attended St. Benno Grammar School together. They also knew each other before their time at grammar school, but only formed 01099 in 2018.
