Sidereal Time
Media type
Organised Sound
4-channel fixed medium

Sidereal time is a timekeeping system that astronomers use to locate celestial objects

Halfway between acousmatic music and «cinema for the ear», with its rugged and crystalline textures, this piece juxtaposes the earthy to the ethereal.
