06In their words
“When it came to the mix, he really brought the song to life, pulling out details and energy we’d overlooked and helping it become the best version of itself. It always felt like a genuine collaboration.”

07The engineer
One nameon everymaster.
Behind that name is a story worth five minutes: three decades from KJM Music Studios to a room floated off its own foundations, and a mastering system built in-house because nothing off the shelf was good enough.
“A one-of-a-kind mastering system built around thirty years on the ears.”
