In April 2023, there was released the first part of the Fluxus edition called Stolen Symphony. The year has come and gone and there is the second part of the Fluxus edition called Keep Together. At the centre of both parts of this edition was a broken piano, acquired by the Opening Performance Orchestra for the purpose of making live and studio recordings. During this time other new works for this broken piano were written by diverse Fluxus and non-Fluxus composers. In the spring of 2022, the Opening Performance Orchestra and broken piano participated in an event hosted by Mieko Shiomi. This was a new version of her early work Spatial Poem, documentation of which was presented at the 2022 Aichi Triennale in Tokyo. At present, broken piano lies in the open air in Prague and is subject to gradual decay.

These both parts of this edition contain 73 new and old pieces, live and studio recordings, finished pieces and scores to be performed, solos and pieces for ensemble, using classical and special instruments from 33 Fluxus artists, which have been played by 10 soloists and 4 ensembles. There are new essays and articles from 15 writers on the theme Fluxus, original photos and other documentation in the booklets.
