404 is a sound art project by Dutch visual artist Joost van Ophem. As 404 he experiments with moods, drones and video in connection with music. His visual work always carries a strong element of social commentary and this is present in 404 as well, be it more subtle and more abstract.
He performs the pieces using a guitar, an amplifier and a beamer.
