This book is an account of art works made between 1997-2002 that investigated convergences of recorded sound and physical materiality. These activities fused autobiography with wider historical perspectives in an openly interpretive engagement with the symbolism of heritage sites. In addition, I have drawn upon sources such as radio broadcasts together with the digital acoustics of video game parlours to reposition notions of simulation, facsimile and electronic information as so much virtual weight. The projects were formulated as site-specific installations following diverse lines of enquiry, which included an examination of the acoustics of geographical space; travel throughout India and Japan to study sonic relations within architectural forms, and recording at other global locations in furtherance of a project concerned with the enigma of silent spaces.
