Sound recording: 'Cripps: Concerto for Lawnmower + Dog Squeaking Door Echo' Sound recording on compact cassette. Side 1: sounds of dog and lawn mower. The recording starts with barking dogs. A chattering sound, possibly from a lawn mower starts. Barking repeatedly occurs and a few times voices can be heard shortly. The sound of the lawn mower becomes slower and stops followed by the sound of walking on grass, [duration: 9 mins 30 secs]. Side 2: sounds of an old squeaking door. The sounds vary in intensity and length and reverberate sometimes. The squeaking door sound is composed in such a way, that the recording becomes a the quality of a musical/sound piece, [duration: 15 mins 34 secs]. c. 1972-1976
