Ambrose Seddon is one of the featured composers at the 2025 L’Espace du Son, the international festival of acousmatic music in Brussels

The Composers Edition website handily explains the musical term Acousmatic as follows:

A predominately European term Acousmatic simply refers to musical works which exist solely as audio or ‘fixed’ media, now most commonly delivered in high quality digital audio formats such as wav and aiff or on CD or Blu-ray. Created with multiple audio channels they are usually also available in stereo mixes and thus playable in most spaces.

And since 1984 the L’Espace du Son festival has proved to be an unmissable event for acousmatic enthusiasts. This festival returns from 15 to 19 October2025, at the Marni theater in Brussels with a rich and varied programme. This year, seven composers have been invited – Laryssa Kim , Charo Calvo, Theodoros Lotis, François Bayle, Armando Balice, Damian Gorandi, Ambrose Seddon. Each will take a turn at the spatialization desk to present music from their repertoire. 

Ambrose Seddon studied at Goldsmiths College and City University, initially he composed, produced, and performed electronic music, but since 2002 he has focused primarily on acousmatic music composition, although he also creates interactive multichannel sound installations, collaborates on immersive audiovisual projects, and performs improvised live electronic music. He is currently a lecturer in the Media Production Department of Bournemouth University.

In addition there is the “espace du son” competition, where candidates are selected based on their graphical recording of a specified work, this year Inflection Point by Nikos Kanelakis (from the festival’s Métamorphoses 2024 competition. This allows a comparison of their playing styles. They will also also play two works drawn at random the day before from the eight works they worked on from a repertoire of around thirty that was proposed to them, as well as a piece of their choice. This competition, now in its thirteenth edition, gives candidates the opportunity to take charge of a repertoire that is rich in 75 years of works.

Entry is free, according to what everyone decides, to immerse oneself in a flow of music and astonishing lights.
