Inclusion Principle

Inclusion Principle operates in a space between electronics, nu-jazz, contemporary electroacoustic music and free improvisation tending towards a minimalist approach.

Formed in 2006, the group released its first eponymous CD ‘the Inclusion Principle‘ that year, with a second release ‘The Leaf Factory Fallback‘ in March 2010. ‘Third Opening‘ was a radical change in sound; the double cd released in 2015 was constructed in the studio with extensive sound design and arrangements of improvised material. It featured Peter Fairclough, who joined the group between 2014 and 2019. The arkiv documents all live performances of the group, available to stream and download.


For the first performance that started off the project, Martin and Hervé play a similar set up of laptop and woodwinds and yet have a different approach to their instruments. Put together, there is a chemistry that inspire and drive their improvisations towards a wide range of soundscapes.

The choice of instruments and sounds on their palette allows them to dramatically change their music between beat driven electro, minimal and microtonal improvisation via electroacoustic experimentation and nu-jazz.

There is something for all in their music. First and foremost, they share an enjoyment of sound and performance which touches their audience, no matter what style they may adopt.


We decided to base the name on a theory of the research physicist Wolfgang Pauli. We found a correlation in that we both worked with a digital scalpel on fields of microsounds; a science which took both our instruments and processed field recordings a little closer to the chemistry of natural sounds, complete with harmonic DNA sequences and rhythmical fragments quantum-jumping from cell to cell.
We were intrigued by the idea of the ‘exclusion principle’ and decided that Pauli was ‘not even wrong’ in his theory since Martin and Hervé successfully managed to sit together in the same room. In the end, our main source of inspiration will always be deep listening and a fascination for the science of the natural world.
Sometimes, sitting in silence for hours in the crest of birdsongs or in wafts of windy harmony is more profitable than practicing scales. And to a certain extent, each of our improvised performances plays itself as an unspoken intense inner excitement. And we leave it to rest, a little calmer, as if something had happened in the space between thoughts…


Inclusion Principle have released three albums and an archive of live documents, available via the discus website or their bandcamp page.
