MuzZone is a Russian musical instrument store. To promote it with a minimum budget, the agency came up with the idea of using one of the easiest memory aids to get contact details: the business card but adapted to the music industry, in creating a musical business card. The cards were covered with special marks providing a certain consequence of notes. By following simple instructions you can play a melody. Musical business cards were distributed among the shop's visitors and musicians. The cards were also used as a self-sufficient promo tool and were distributed at Cover King, the city's major musical event, which took place in one of the key rock bars.
