This article describes the site-specific performance Lucid Dreams of Mr. William Heerlein Lindley in an acoustically unusual old sawage treatment plant in Prague.
During this event, different kinds of sounds are combined: recordings from various places in Prague, those which are electronically generated, and actual concrete sounds producted by the participants. A part of the event was also a live EBU satelite broadcast Ecotechnical Museum in Bubenec, 10/10/2009, 6 pm.
