Stephen Fruitman wrote a nice review on Broadcasting On Ghost Frequencies by Erstlaub at his website Sonomu.net.
This excellent work was inspired by a bit of quackery known as the ”Ganzfeld Procedure” in the field of parapsychology. A subject is blindfolded and equipped with a pair of headphones playing nothing but white and pink noise – static. Out of this aural assault, it is hoped the subject will discern patterns, maybe even hear voices. Maybe even real voices from the past.
