In this recorded
sound performance, the artist plays a trumpet — one type of musical horn — to imitate car - related
sounds; the performance comprises a series of perceptual shifts between
figure and ground within an automotive soundscape — keynote or
ground sounds (the hum of a motor) are speckled with soundmarks (the
sound of screeching tires, the
sound of a transmission shifting gears)
and, in some moments within the composition, drift entirely into signals (the
sound of a siren, the
sound of an engine blowing out).
