This issue of Organised Sound is devoted to a conference, ‘Music without Walls? Music without Instruments’, which took place at De Montfort University, Leicester, UK in June of this year. It was hosted by the university's Music, Technology and Innovation Research Group. As one can easily discover, given the conference's title, the goal of this meeting was to investigate vision and plans for the future. The three-day event included papers, musical events, installations, demonstrations and a plenary. All artists whose pieces were selected for the conference concerts were requested to present vision papers to accompany their performance.
