FOR THE MUSIC
Reflections From a Journey
Music has a remarkable way of bringing people together.
Three years ago, when Treble Clef Audio® was introduced during Copenhagen's 3daysofdesign festival, I could never have imagined where that journey would lead. The ambition was simply to explore how science, engineering, psychoacoustics, craftsmanship and design might help people experience recorded music with a deeper sense of presence and emotional connection in the home.
What followed was never part of a plan.
One conversation led to another. One listening session became the next. Every encounter brought new perspectives and a deeper appreciation of the extraordinary people whose dedication allows recorded music to move us long after the performance itself has ended.
Looking back, I realise these experiences have shaped Treble Clef Audio® every bit as much as the engineering.
These are a few of those moments.
Brandee Younger
Gadabout Season
In May 2025, we were fortunate to host an intimate pre-release listening session in New York for Brandee Younger's Gadabout Season.
Before the album reached the public, Brandee, Rashaan Carter and invited guests gathered to listen, reflect and discuss the music in an atmosphere where every detail mattered.
Just over a year later I attended Brandee's concert in Copenhagen. Afterwards she signed the front cover of my copy of Gadabout Season with a short handwritten message.
I didn't think much about it until I looked at the album again a few days later.
Joy and Resistance
Later that year we had the privilege of contributing to the Doris Duke Foundation's Joy and Resistance Press Listening Event in New York, celebrating Terri Lyne Carrington's We Insist 2025! together with Brandee Younger's Gadabout Season.
The evening wasn't simply about listening.
It became a conversation between artists, journalists and invited guests, exploring music, culture and the ideas behind the recordings.
It reminded me that listening is rarely a solitary experience.
The best music naturally creates dialogue.

From Rudy Van Gelder Studio to the Listening Room
Some of the world's most influential jazz recordings have been created at Rudy Van Gelder Studio. Recording there with Joe Lovano, Sam Yahel and Kresten Osgood was already an unforgettable experience.
A few days later, Maureen Sickler who recorded the session, and Don Sickler joined us in New York to hear the session replayed through the TCA-M.
Listening together, the loudspeakers quickly disappeared from the conversation.
The focus moved naturally towards the performance, the recording techniques and the subtle decisions that shape how music reaches the listener. One of the most memorable moments came when Maureen immediately recognised the distinctive acoustic character of Rudy Van Gelder Studio, a sound she had come to know through decades of listening and working in that remarkable space.
That afternoon reinforced something I have often reflected upon since.
Faithful reproduction begins long before anyone designs a loudspeaker.
The Village Recording
The journey of that recording continued
Thomas Vang mixed and mastered the Rudy Van Gelder Studio session at The Village Recording in Denmark, working together with producer Kresten Osgood.
Today the recording forms part of the Treble Clef Audio Private Vault, an exclusive collection of recordings used during customer demonstrations and listening sessions.
Following a recording from the studio, through production and finally into the listening room has given us an appreciation of the entire creative chain that simply cannot be learned from science, engineering and measurements alone.
ECM Records
Before the Music Meets the World
Our collaboration with ECM Records provided another memorable experience.
As part of ECM's Press Listening Party for Joe Lovano's debut Paramount Quartet album, the TCA-M provided the reference playback system while Caroline Fontanieu, Senior Director, Marketing & Strategy at ECM Records, led a conversation with Joe Lovano and the quartet musicians: Julian Lage, Asante Santi Debriano and Will Calhoun about the music, the recording and the creative process.
The Press Listening Party formed part of ECM's introduction of an important new release to the music press before the album reached listeners around the world.
Watching musicians and the record label share the creative journey behind a recording before its public release offered a rare perspective. The music was still new, the artistic decisions remained close to the surface, and every conversation reflected the care that had gone into bringing the album to life.
Simply being present for that process was a privilege.
Cooper-Moore
Craft Beyond Disciplines
One of the most memorable afternoons took place at Carl Hansen & Søn in New York with the extraordinary Cooper-Moore.
Surrounded by handcrafted furniture, handcrafted musical instruments and music, the conversation moved effortlessly between creativity, materials and craftsmanship.
It became clear that whether shaping wood into furniture, building instruments or designing loudspeakers, the underlying motivation is remarkably similar.
Thoughtful craftsmanship creates experiences that endure.

The Banjo, stripped to its bare essence, offered rhythmic defiance and Appalachian truth amplified by the TCA-Ms.
Gilbert Holmström
Music Across Generations
During the Copenhagen Jazz Festival we welcomed Swedish jazz legend Gilbert Holmström to an intimate listening session at the Sing Tehus Listening Bar.
As recordings from the late 1950s to the 1980s filled the room, Gilbert shared memories of Charlie Parker, Sonny Rollins, Keith Jarrett and the musicians who had inspired him throughout his remarkable career.

Listening to those recordings while hearing Gilbert's own recollections brought another dimension to the experience.
History was no longer something preserved in books or recordings.
It became immediate. Human. Alive.
I found myself reflecting on how extraordinary it was to sit beside someone whose musical life reaches back to a time when I was simply a young child, with no idea that music would one day shape my own life in such unexpected ways.
Looking Forward
Looking back over these experiences, I don't see milestones
I see people - Musicians - Recording engineers - Producers - Designers - Craftspeople & Listeners.
Each has contributed, in one way or another, to a deeper understanding of what recorded music can become when every link in the creative chain is treated with care and respect.
Treble Clef Audio continues to evolve through those encounters
If our work helps listeners feel a little closer to the musicians, the performance and the emotion that inspired a recording, then every conversation, every collaboration and every listening session has been worthwhile.
As I was writing this looking once again at the front cover of Gadabout Season.
Brandee had written:
"Dear Ole. Thank ya for all that you do for the music!"
I smiled.
Because those few handwritten words somehow expressed the journey better than anything I could have written myself.
