At a concert in London last week rock band Ok Go performed with guitars customised by London designer Moritz Waldemeyer featuring LEDs and lasers. Originally created as part of a design performance for fashion brand Fendi at Design Miami in December, the instruments use lasers to create imagery on a video screen in response to the music. Bringing together the creative worlds of industrial design, rock music, installation art and haute fashion, Waldemeyer has customized a selection of Gibson guitars, outfitting each instrument with laser lights, interactive LEDs and off-cut FENDI materials. When the guitars are played, the lasers engage a video wall and leave traces that illustrate the music in real time.
