UK reader Adham Fisher, who recently visited all 301 Paris Metro stations and wrote a song about the quest, announces a musical project:
[I asked] different musicians to submit songs about various metro systems around the world. The result is the Metro EP under the collective name 1000 Stations. We toured it to Paris last month and hope to release it early next year. The project may be followed here: twitter.com/1000stations .
It would be great to see more musicians trying capture the beauty of networks in musical form. Music is mostly math anyway — especially electronic music — and as many composers have discovered, you can make great music simply by exploring music's mathematical structure. Geographic networks have structures too, that could be explored by analogy at various degrees of abstraction or popularization.
Storing and transmitting geographical information in songs is not a new idea, especially for premodern cultures. That's part of what Australian Aboriginal songlines are, for example.
