This is a piece of modern art entitled "Where are we going to dance tonight?" by the Milanese artists Goldschmied & Chiari.
This installation was, until recently, standing in the Museion modern art gallery in Bolzano. It was a takedown of the lavish, hedonistic lifestyle enjoyed by the Italian political class in the 1980s.
It is, according to the museum's website, "a site-specific work staging the scene after the end of a party: the perfect metaphor for the decade." According to the artists, "the work, which is only visible when the museum is closed, from dusk till dawn, shows the aftermath of the party, the leftovers of the feast: the metaphorical tree of abundance in ruins."
Or it was, until the museum's cleaners put it in the bin by accident.
According to a Facebook update from the museum, it'll be reinstated "as soon as possible".
