Nigel Stanford is a New Zealand musician who creates sound experiments using mechanics and technology. The music video for the title track on his new album, Automatica, was made by two thin orange boys: industrial robots.

Or, well, it looks like it was made by the robots. In fact, the robots aren’t playing the music you can hear — instead, a combination of special effects and sped-up footage was used to make it look like they are. Stanford told The Verge that the video is essentially a performance, although the music was specifically written to sound like something the robots could play.
