All audible and inaudible sounds in the universe are an inspiration for my music, such as physical movement, art, architecture, good food, electronics, quantum physics and nature.

My focus is on experimental, improvisational and contemporary music. As an improviser I’ve made recordings and/or performed at festivals with Michael Moore, John Butcher, Joost Buis, Ken Vandermark, Paul Dunmall, Xavier Charles, Han Bennink, Françoise Rivalland, Hamid Drake, Fred Frith, Hilary Jeffery, Tewolde Brhane Girmay, Getatchew Mekuria, Franz Hautzinger, John Tilbury.

2020 Le UN, improvisation company. Each of us is committed to artistic achievement as much as to the social, non-hierarchical organization of the whole. Le UN brings together 21 musicians, 2 filmmakers and 1 light artist, 1 performer, depending on the context. It is the individual and her/his practice that are at the centre of this orchestral experimentation and not her/his dilution in the collective. It is important for us to preserve our singularity within a protean mass without obstructing the collective space. Le UN improvises (Nodal Unit), invents play devices (Espace tendu, Mottes), works with the cinematographic image (Unkino), and is based in Bordeaux.

2019 Dromedary, a duo with Trombone player and composer Hilary Jeffery. Having worked together for more than 12 years in many projects, Hilary and I formed Dromedary in November 2019 to play improvised modal music. Key themes for our work include consciousness, inner-space, tuning, expanded listening, presence and multi-dimensionality.

Since 2008 I am part of the pool of musicians of Lysn, a band formed and led by trombonist Hilary Jeffery. The band has a variable line-up, he describes the music as "improvised drone-jazz for inner/outer space”.

2007 to 2011 Oliver & Heggen, a duo with violinist/violist Mary Oliver.

Cooperation with choreographers Lily Kiara 2006 to 2010 and 2020 till now, Marek Jason Isleib 2018, Hisako Horikawa 2003/2004 and 2011, Julyen Hamilton 2007, Magpie Music Dance Company 2005 to 2010, Sylvain Prunenec 2001 to 2003.

1997 to 2019 member of the Nieuw Ensemble with tours through China, Korea, USA and Europe. New Chinese music is this ensemble’s specialty.

I have worked in many orchestras and ensembles for contemporary music, such as the Royal Concertgebouw Orchestra, the Rotterdam Philharmonic Orchestra, the Radio Chamber Orchestra, Asko/Schönberg Ensemble.
