A variable number of music boxes with popular and classic music are installed on a wall in rhizomatic form. This work generates a participatory/public moment of interaction with an audience that can either choose to activate it or let it be silent, to collaborate, mechanically, with one another to create a polyphonic sound, or simply ignore to participate. One Thing And Another takes a form other than sequentiality: a propagative desiring molecular distribution of each element in the series (i.e. musical box). The formation traced by the installation is accessible from whatever point and doesn't have a beginning or an end; the conjunction 'AND' in the title of the piece - inspired by Donald Judd piece One Thing After Another - stresses the virtuality of life-as-intermezzo .
