Mixing & Mastering Engineers, Producers & Songwriters who worked with just_leben
With five years of experience at a record label (Universal Music) and a strong background in sound engineering, I've had the privilege of contributing to numerous songwriting camps for African musicians right here in Johannesburg. In 2025, I embarked on my journey as a solo artist, collaborating with talented producers to craft vibrant tracks.
