The cartographic sound of the city

What does Amsterdam sound like when using its street plan as a map? (June 2003)

I made this instrument with loose parts. The metal combs come from the music instrument repairer of museum ‘van speelklok tot pierement’ (Utrecht). As for music role, I placed a sticker sheet (printed in negative) of the street plan on the copper cone so that only the buildings were pasted on the cone, after which I placed it in an acid bath for several days so that the copper could corrode there where no building are present. After this, I coated the copper cone.
