Grauton is Karen Geyer, is a sound artist / instrument builder working between Zurich and New York. Zwischen is her second release. She invents self-made, mechanical objects, whose sounds she amplifies with contact microphones and sends them to a mixing console where she conducts the sounds like an orchestra. The instruments are built with everyday objects such as bicycles, fans, water heater, stool or electric motors, with simple materials like wood, wire, rubber, silk or paper tape.
