Technology that blocks with dust and slows down the synchronisation is natural sabotage that time creates through deposits and layers.

The last movement of “Roland Ultra” of 1968 is performed while an operating machine prints a poster by Luca Pancrazzi, which is then distributed to the public.
The improvisation is structured around the movement of the machine during the printing, the musicians reproduce the sounds made by the workers adjusting the color regulators.
The public takes part by keeping their own taperecorders on, reproducing and spreading the sound produced by the rotating machine throughout all the space.
