We are unable to provide you with either the principle or the meaning of this 21st edition of sonic and non-sonic performances (culinary art or telepathy are included, and there is even some songwriting!) Anyway, please find below the descriptions of the mind-boggling proposals that await you, selected by six volunteer listeners, and presented in the supposed order in which they are to take place. One can only hope to find some coherence in the whole, but good luck with that. Experimental? Okay, maybe. Not as a musical genre, but as physical as well as conceptual, enthusiastic as well as critical, collective as well as polyphonic ways of putting an end to moral, political and musical harmonisation programmes. Long live noise and its unthinkable freedom of choice.
