Jo Caimo is a visual artist, musician, radio maker, and inventor of superfluous objects and instruments. His work situates itself in the margin between performance, music, installation and the digital world. In many works he tries to define a border of a medium (or object) or a border of our senses. This can go from a website with the recordings of the sound of every position of a metronome (to create your own metronome symphony online) towards the ‘unstable’ live performance of swallowing a bluetooth-microphone (to record the audio of his whole digestive system, to which you are invited to call), or by putting the sun live on the internet (for rainy days, some placebo Vitamin D).
