The trio

An unusual combination: a piano player who studied classic and modern composition, a sax and clarinet player who learned to play in a band club, switched to east european music and  ended up in jazz, and an experimental pop minimalist  playing the upright bass. They have know each other since they were teens and back then they played together in several bands (the Urge, Two Gentlemen, Masters & Johnson, Dutch Distress).
In 2015 they reunited to focus on the core of all music: communication. They play 100% improvised music, with no agreements on scales, chords, tempo or beat... It is all about listening to and interacting with each other. Breaking the silence. Slowly, cinematic, melancholy...

The complete improvisation sessions are recorded on a simple multitrack recorder, afterwards the best parts are selected and mixed.
Six albums have been released; Harbour, Industry, Home, Slow, the Lasso of Time and Lost on the Moon.
You can find these albums on iTunes, Spotify, Amazon and other digital services, see links below (click icon to visit service)



You can book the Unheard Music Concepts trio for live performances. We play a selection of tracks from our albums live, improvised.
This means that no performance is the same, and that although you’ll recognise the tracks, they’ll take a different path each time they’re played. 
You can also book us for seminars, conferences, openings, etc.

The only thing you need to do is inform us where and when it was used, and you need to mention the artist ‘Unheard Music Concepts' and track name in the credits.
We made it available under the Creative Commons license ‘BY', but added the non existing ‘NAD' because we discovered that what we have in mind doesn't exist as a CC license.
NAD stands for "No Audio Derivates' In other words you can freely use (part of) our tracks in a film or video, but not remix or re-use part of our tracks in other musical work without our permission.
