Peter & his Possy 

Peter's Possy was originally built as a commissioned piece for an exhibition entitled "Les Mécaniciens de l'imaginaire" at "La Cité Des Sciences et de l'industrie de La Vilette" http://www.cite-sciences.fr in Paris 1987. The pneumatically powered quartet is piloted by an industrial robot. A bass produces groaning metallic sounds when industrial sized, stretched, band saw blades are bowed with rubber inner tubes. Percussion is provided by an array of chromed car fenders. A wind instrument combining an old cooling system, stretched bicycle inner tubes, a steam iron and a nice piece of marble, produces piercing trumpet like sounds. An old upright piano has been dismantled and rebuilt to generate "prepared" sounds with the help of a model truck which rolls up and down the reconditioned keyboard cover.
The soundtrack you are listening to (if you have the sound turned on) is extracted from the video Peter & his Possy an was made in collaboration with Dirk Offringa.
