Welcome to Kelsey Mastering

The thrill of finding each song’s unique aesthetic has always been the joy that being a specialist audio mastering engineer brings me – regardless of the genre.

From Pop, Rock, Rap, Jazz, Gospel and Musical Theatre to traditional and emerging African genres like Maskandi, Gqom and Amapiano, I have helped shape the sound of South African music since 2003.

I’ve mastered thousands of songs, including work for groundbreaking artists like Bongeziwe Mabandla, Eddie Kenzo, Culoe de Song, aKing, Van Coke Kartel, Taxi Violence, Black Coffee, Sun-El Musician and Tresor.

I’d love to join you for the next part of your musical journey – on a quest for the perfect sound.

Matthew Fink Label Manager/ Producer / Just Music

Rogan has mastered several projects for the Just Music label ranging from delicate indie folk to harder electro beats and psych/garage rock. I enjoy that fact that he takes such care and effort for each assignment tailor crafting the tone, compression and image to best suit the genre and overall feel of the song. He is a pleasure to work with and quickly grasps the headspace we initially recommend on a new project before adding his own signature sound that we trust and enjoy.
