Austrian designer Katharina Hölzl created an ingenious perforated business card for the band Ritornell, that when played through the accompanying music box, produces music. To hear the card, watch this video demo by Richard Eigner of Ritornell.
Ritornell’s business cards are inspired by the project’s live show. The improvised concerts evoke a lively atmosphere by the combination of filigree electronics with playful timbres of diverse acoustic instruments and utensils such as egg whisks, toilet brushes, chopsticks or sewing needles. As an integral part of their set list, Ritornell invites the audience to bring along their private musicboxes. Arranged in a big circle, the players’ speed of turning levers is conducted: the results are as shimmering as you would expect.
