In 2007, Joseph Bertolozzi went to a bridge over the Hudson River near Poughkeepsie and “hammered on I-beams and guardrails, whacked thick cables, sent steel pellets down the inside of a bridge tower and recorded the sounds … [and] turned them into a composition, Bridge Music..” He has now asked the city of Paris for permission to do a similar project with the Eiffel Tower for the structure’s 125th anniversary in 2014 – and the city is seriously considering it.
