Allison Swank The Swank Group JBS Music Design Testimonial

JBS has an uncanny ability to intuit the sound and mood for a piece almost before I even send him the brief – that is why he is always the first composer I call for any project. His quick turnarounds and reliability are icing on the cake.

Nthato Mokgata Spoek Mathambo JBS Music Design Testimonial

JBS has been invaluable in the refinement and production of all of my musical projects  for the past 4 years. We have completed three full length album as Spoek Mathambo, Fantasma, Batuk as well as a couple of EPs.  Through his innovative mixing and production concepts we have broken a lot of creative.

JBS has helped us create a very strong and original sound for Fantasma. We call him Ndlov’enkulu (Giant Elephant).

Montle Moroosi Wet Dreams Recordings JBS Music Design Testimonial
It’s not very often you find a sound engineer with both the creative competencies of a producer and the stoic qualities of a thorough professional sound engineer. We’ve used JBS for three projects and he understands our aesthetic. And the best thing is the turn around time; 8 tracks fully mastered in two days and I didn’t send any back for changes.

A great and imaginative mixing engineer. It was really fun working with JBS on Musica Da Terra, and it’s been a pleasure to start work on a new album with him.
