Raw in.Ric Hertz.Record out.
Between your mix and the world sits one pair of ears — thirty years at the faders, work with Mott the Hoople's Verden Allen and Lacuna Coil's Marco Barusso. No juniors, no presets. Ric signs every master himself.
02Monitor

03The room
Built for one thing: accuracy.
A fully decoupled room-in-a-room floating build, treated with Rockwool RWA45 and RW3 rigid slab behind fabric walls, so the low end stays honest from first reflection to the modal region. None of it masters anything on its own — it's what lets Ric hear the record properly and judge every track against the same truth.
Upload a track to an AI master and you get the average of everything the model was trained on — fine for a demo, wrong for a release. Every curve here is shaped by a person who sits with the song, knows the genre, and can explain every move — turnaround takes as long as the song needs, not minutes.

“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. The full tour is one click away.
A one-of-a-kind mastering system built around thirty years on the ears. It isn't sold, licensed or rented — the only way to hear what it does is to send a track.
08Output
Send one track. Pay nothing.
New clients get the first half of one track mastered free. If the test master doesn't move you, walk away — no invoice, no hard feelings.
