This audio comes from a cassette tape I found at a thrift shop. Since the store owner did not know what content the cassette contained she gave it to me for free. It is 38 minutes of a strangely rhythmic pulsating continuum. There was probably music on this cassette but it gave way to the tape’s deterioration. It reminds me of how cassette tapes, recorded over multiple times, sometimes let the previously recorded songs bleed through, emerging from the silences between the songs recorded on top of them. What survives of this tape could be a base track for something more substantial. Or it could just be an annoyingly irregular, seizure-inducing heartbeat type of sound used in torture chambers.
