To celebrate its 10th edition L’Espace du son, the international festival of acousmatic music in Belgium, invited several pairs of composers to confront their distinct musical approaches. Each night, the public will be treated to two styles, two sensibilities that will stress the diversity in acousmatic music. On November 14, 2003, French Bertrand Dubedout and Canadian Sarah Peebles will compare their sonic impressions of the Japanese cities of Nara and Tokyo. November 15, its the gentle and meditative music of Swede Erik Michael Karlsson against the nervous and dynamic work of Philippe Mion. And finally, the 16, time for Elsa Justel’s granular sounds and Ludger Brümmer’s energy modelisation.
