Two tape loops run on four old reel to reel tape machines. While two of the machines are constantly recording the sound in the space with microphones, the other two devices simultaneously play back that recording, echoed, which is then also recorded, and so on.
This work is a play on the hypothesis that the tape recordings of spaces may sometimes contain messages from the beyond. This is known as "Electronic Voice Phenomenon" or "Tonbandstimmen". It is a test to discover if there are any ghosts still lingering in the space communicating to us through the echos of our own utterances.
