In 2001 I coordinated a conference, along with my former colleague, Andrew Hugill, at De Montfort University called ���Music without Walls? Music without Instruments?���. This international conference formed part of the launch of the then Music, Technology and Innovation Research Group (now Institute). My contribution to that conference was what I called ���a conference provocation��� entitled ���From Algorithmic Jukeboxes to Zero-time Synthesis: A potential A���Z of Music in Tomorrow���s World��� (Organised Sound 6(2): 91���96, 2001). For EMS21 I return to the notion of a ���conference provocation��� and create a second ���potential A���Z��� focusing on this year���s EMS conference theme, namely Future Directions of Electroacoustic Music Studies. Given the 20��� duration of a conference talk, the 26 ideas will be briefly presented including a statement why each area might serve the future of the electroacoustic music studies domain. Each one of the 26 will represent under-developed areas in the field, sometimes presented formally, sometimes critically and sometimes humorously, thus a provocation in the form of food for thought.
