The research platform SIMM was created as an independent organisation in 2017, but activities of SIMM started already in 2015: In October 2015, the SIMM staged its 1st international SIMM-posium in Ghent (Handelsbeurs) and Brussels (Kaaitheater). Leading representatives from the fields of musical practice and research met and exchanged their experiences, focussing on the possibility for scientific research on the possible role music-making can play in social and community work. In 2017 SIMM then accompanied the organisation of the 2nd SIMM-posium in London (July 2017). This time, the SIMM-posium was organised by the Guildhall School of Music and Drama, and in a close collaboration with Royal Holloway (University of London). The aim was to demonstrate that – although SIMM was at its start a Ghent University and University College based initiative, and continued to be administered from Belgium out – we planned to work with and in other countries and continents. The 3rd SIMM-posium was organized in Porto (May 2018) by CIPEM. In July 2019 SIMM succeeded to have its first SIMM-posium organised outside of Europe: the 4th SIMM-posium was organized and held at the Bogota (Colombia) based Fundación Universitaria Juan N Corpas, thus making clear how important SIMM-research in the global south is to the platform. The 5th SIMM-posium is organised during weekly online sessions from 12th January until 9th March 2021 in coproduction with the centre for fine arts BOZAR in Brussels. On 2 and 3 November 2021 the 6th SIMM-posium was held at and organised in Paris at the Philharmonie de Paris, in a close collaboration with the Fondation Royaumont. On 12, 13 and 14th December 2022 the 7th SIMM-posium will again be organised in London at the Guildhall School of Music and Drama: It will include an extended session devoted to the outcomes of the AHRC/SIMM-funded international comparative research project developed since 2020 in 4 countries (UK, Finland, Colombia and Belgium). And in November 2023 the 8th SIMM-posium will be organised in Brisbane, Australia, by the Queensland Conservatorium Research Centre (Griffith University).
