In 1973, the Sound Sculpture Show took place at the Vancouver Art Gallery. An LP audio catalogue (with a booklet) of the exhibition, entitled “The Sounds of Sound Sculpture”, was released in 1975 under the supervision of the Canadian sound sculptor John Grayson and US composer David Rosenboom. Grayson had edited an important early book on the field, “Sound Sculpture”. The LP included rare takes of Rosenboom and Grayson, amongst others, playing famous pieces by pioneering sound sculptors including the Baschet brothers and Harry Bertoia, the latter best known for his Sonambient series. It also included some of the few recordings by Stephan Von Huene, who had begun to create his kinetic sculptures, and the profound atmospheric pressure systems constructed by the New York sound artist David Jacobs. The LP comes complete with a booklet of visually arresting photos and other materials about these historic sound sculptures.
