Lock concerts on the Danube

 European Sound Delta  (Summer 2008) was a boat journey on two of Europe’s most densely  trafficked rivers, the Danube and the Rhine.  Over Summer 2008 two boats sailed slowly upstream from the Black and North Seas to the final destination point in Strasbourg. Along the way resident artists composed sound pieces and experimented with alternative forms of radio inspired by the journey. With the radio artists Knut Aufermann and Sarah Washington we joined the boat from Linz (Austria) to Regensburg (Germany) and begun to research the use of basic sonar techniques and echo location to try and to make an audio image of our surroundings. We used a very simple sonar system consisting of speakers facing out from the boat, megaphones and microphones that picked up the reflections from the shoreline and the concrete walls of the locks.

 As we drifted past walls, boats, walkers, fishermen, cyclists, under bridges, and trawled through the some of the largest locks in Europe, the reflected sound created an audible map of the ongoing journey.

You can hear some of our recordings made in the locks here.
